Learn Quadratic Equation Formula Maths Class 10 here for better understanding of the chapter.

Answer»
ax2+bx+c=0

Quadratic Equation

Before studying about this topic let’s know the word “quadratic” came from “quadratus” means square.

An algebraic equation or polynomial equation with degree 2 is said to be a quadratic equation.

It is represented in terms of variable “x” as ax2 + bx + c = 0. This form of representation is called standard form of quadratic equation.  where a, b, c are real numbers and the important thing is a must be not equal to zero.
As Example:
, 8x2 + 5x – 10 = 0 is a quadratic equation.

Root of quadratic equation:

Root of a quadratic equation ax2 + bx + c = 0, is defined as real number α, if aα2 + bα + c = 0. The zeroes of the quadratic polynomial and the roots of the quadratic equation ax2 + bx + c = 0 are the same.

Solution of a Quadratic Equation by different methods:

1. By Factorisation:

First thing to keep in mind that If we can factorise ax2 + bx + c, a ≠ 0, into a product of two linear factors,
then we can find the roots of the quadratic equation ax2 + bx + c = 0 by equating each linear factor to zero.

2. By Completing Square:

The term completing the square in algebra is to form the given term in squared units by the use of algebraic identities.

x+ 2mx + m2 = (x + m)2

By this algorithm, we can find the roots easily. One of the fact to remember that when square root is opened in number it uses simultaneously both + as well as – sign. Thus two roots is defined.

3. By use of quadratic formula:

In the standard quadratic equation ax2 + bx + c = 0,

if the determinant b2 – 4ac ≥ 0

then root of quadratic equation is given by quadratic formula as

x =\(\frac{-b±\sqrt{b^{2}-4ac}}{2a}\)

Examples related to quadratic equation

  • Solution by factorization examples:
  1. Find the roots of the quadratic equation 6x2 – x – 2 = 0.

Solution:

6x2 – x – 2
= 6x2 + 3x – 4x – 2
= 3x (2x + 1) – 2 (2x + 1)
= (3x – 2)(2x + 1)
The roots of 6x2 – x – 2 = 0 are the values of x so that (3x – 2)(2x + 1) = 0
so, 3x – 2 = 0 or 2x + 1 = 0,
i.e. x = \(\frac{2}{3}\) or x = \(\frac{-1}{2}\)

So, roots of equation are \(\frac{2}{3}\) , \(\frac{-1}{2}\).

  • Solution by completing square examples:
  1. Find the roots of the equation 5x 2 – 6x – 2 = 0 by the method of completing the square.

Solution:

To solve it we first multiply the equation throughout by 5
25x2 – 30x – 10 = 0
This can be also written as
(5x)2 – 2.(5x).3 + 32 – 32 – 10 = 0
(5x – 3)2 – 9 – 10 = 0
(5x – 3)2 = 19
5x – 3 = ±\(\sqrt{19}\)
5x = 3 ± \(\sqrt{19}\)
x = \(\frac{3 ± \sqrt{19}}{5}\)

So, the roots of equation are \(\frac{3 + \sqrt{19}}{5}\) and x = \(\frac{3 - \sqrt{19}}{5}\)

  • Solution by Quadratic formula examples:
  1. Find the roots of the quadratic equation, 3x2 – 5x + 2 = 0 if it exists, using the quadratic formula.

Solution:

In this equation 3x2 – 5x + 2 = 0, a = 3, b = -5, c = 2
let’s first check its determinant which is b2 – 4ac, which is 25 – 24 = 1 > 0, thus the solution exists.
by applying quadratic formula x =\(\frac{-b±\sqrt{b^{2}-4ac}}{2a}\)
we have, x = \(\frac{5 ± \sqrt{1}}{6}\) = \(\frac{5 ± 1}{6}\)
i.e, x = 1 or x = \(\frac{2}{3}\)
so, the roots are \(\frac{2}{3}\), 1 etc.

Define nascent hydrogen. Prove that nascent hydrogen is powerful reducing agent than molecular hydrogen.

Answer»

Nascent hydrogen is a concept that was once invoked to explain dissolving-metal reactions, such as the Clemmensen reduction and the Bouveault–Blanc reduction. Since organic compounds do not react with H2, a special state of hydrogen was postulated.

Nascent hydrogen is most powerful reducing agent than molecular hydrogen because nascent hydrogen is in atomic state and atoms are more active than molecules, nascent hydrogen is evolved in small bubbles containing the gas under great pressure, nascent hydrogen is activated by the energy liberated in the reaction in which it is formed, so the nascent hydrogen becomes more energized and active.

Describe the role of Martin Luther in the Reformation Movement.

Answer»

Reformation began in Germany and its leader Martin Luther was born at Eiselben in 1483 A.D in a poor German peasant family. Luther studied theology, law and humanism at the University of Erfurt in 1508 A.D. He was always haunted with the question, “how to please God?” Lie . seriously studied the Bible and the works of St. Paul and St. Augustine. He became a Professor of Theology in the University of Wittenberg. Luther strongly believed that man could get salvation only through God’s mercy but the Church preached that it possessed the means of salvation. He rejected the doctrine of good work.

He visited Rome in 1511 A.D and was shocked at the worldliness of the Pope and the corrupt and immoral life led by the clergy. He did not to tolerate the corrupt practices of the Church. In 1517, Pope Leo-X sent out several agents to dispense indulgences in order to collect funds to complete St. Peter’s Basilica in Rome. They spread the belief that indulgences were passports to heaven. One of these agents, John Tetzel was selling indulgences as passports to Heaven.

Luther’s opposition: Luther wrote his objection against the Church practices and Pope’s authority in Latin. He prepared his objections in the form of ‘95 Theses’ and posted them on the door of the Church in Wittenberg, Thereupon Luther started a rebellious Movement against the abuses of the Church. This popular revolt came to be known as Protestant Movement.

Luther questioned the authority of Pope and challenged the concept of infallibility. As a result of these activities, the Pope ordered Emperor Charles-V to take action against Luther. In 1521 Charles-V summoned the Diet of Worms and ordered Luther to appear before the Diet to justify the charges made against the Pope. In the Diet of Worms, Luther was excommunicated by the Pope. He was expelled from the Church and was branded a heretic.

DuPont analysis is an expression which breaks _______ into three parts.1. Gross Profit2. Return on Equity (ROE)3. Net Profit4. Current Asset

Answer» Correct Answer - Option 2 : Return on Equity (ROE)

The correct answer is Return on Equity (ROE).

  • The DuPont equation is an expression that breaks return on equity down into three parts:
    • profit margin
    • asset turnover
    • leverage
  • By splitting ROE into three parts, companies can more easily understand changes in their returns on equity over time.
  • As profit margin increases, every sale will bring more money to a company’s bottom line, resulting in a higher overall return on equity.
  • As asset turnover increases, a company will generate more sales per asset owned, resulting in a higher overall return on equity.

Deficiency of what causes Marasmus disease.

Answer»

“Marasmus can be defined as a form of nutrition deficiency disorder, usually occurring in children. It can be life-threatening if not diagnosed at an early stage.”

Causes of Marasmus:

As mentioned above, it is a nutrition deficiency disease and is mainly caused by:

  • a severe deficiency of protein, vitamins, minerals, carbohydrates, and lipids.

  • Viral, bacterial, and parasitic infections are also a major cause for this disorder.

  • Children, older adults, and people with a weak immune system are more prone to marasmus.

Other causes of marasmus include:

  • Poverty

  • Starvation

  • Famine or unavailability of food

  • Lack of education about nutritional requirements.

  • Intake of medicines that interfere with the absorption of nutrients.

Symptoms of Marasmus:

The symptoms of marasmus are more common to the symptoms of kwashiorkor, which includes:

  • Dizziness

  • Weight loss.

  • Dehydration.

  • Lack of energy

  • Stunted growth.

  • Chronic Diarrhoea.

  • Shrinkage of Stomach.

  • Respiratory infections.

  • Dry skin and brittle hair.

  • Underweight or loss of muscle mass and subcutaneous fat.

Risk Factors of Marasmus:

The risk factors for marasmus include:

  • The people living in developing countries are more at risk of contracting marasmus.

  • The famine and poverty struck areas have a larger percentage of children suffering from marasmus.

  • If the infants are not breastfed by nursing mothers due to malnutrition, the risk of marasmus increases in children.

  • Insufficient medical care and high disease rates are other reasons that increase the risk of marasmus in the population.

Diagnosis of Marasmus:

This deficiency disease can be diagnosed by the physician through a physical examination such as:

  • Skin test for the functioning of the immune system.

  • A blood test to check for the presence of any microbial infections.

  • Height, weight and physical activity of a child according to age.

  • General counselling of a child to study the child’s mental state and behaviour.

  • Urine and stool test for examining diarrhoea and other nutritional deficiency disorders.

Treatment for Marasmus:

The first and primary treatment prescribed for the patient suffering from marasmus includes:

  • Multivitamin supplements to improve appetite and nutrition deficiency.

  • Dehydration symptoms can be prevented by the intake of water and other fluids that contain electrolytes.

  • Few antibiotics or other medications are given to treat children with pathogenic infections.

  • A well-balanced diet is given once after the child’s condition is stable and starts to recover slowly.

  • Diet rich in protein like skimmed milk, and other energy providing food supplements to increases the energy content.

Two conducting plates M and N, each having large surface area A (on one side), are placed parallel to each other in figure. The plate M is given charge `Q_1` and N, charge `Q_2(ltQ_1)`. Then A. electric field at point A is `(Q_1-Q_2)//2Aepsilon_0` toward right.B. electric field at point B is `(Q_1-Q_2)//2Aepsilon_0` toward right.C. electric potential of N is greater than M.D. all of the above

Answer» Correct Answer - A::B
a.,b.
Electric field lines will be from `M` to `N`, so potential of `N` will be less than that of `M`.

In figure , the plates of a parallel plate capacitors have unequal charges. Its capacitance is C. P is a point outside the capacitor and close to the plate of charge -Q. The distance between the plates is d. Then A. a point charge at point P will experience electric force due to the capacitorsB. the potential difference between the plates will be `3Q//2C`.C. the energy stored in the electric field in the region between the plates is `9Q^2//8C`.D. the force on one plate due to the other plate is `Q^2//2piepsilon_0d^2`.

Answer» Correct Answer - A::B::C
a.,b.,c.
i. `E=(2Q)/(2Aepsilon_(0))+(Q)/(2Aepsilon_(0))=(3Q)/(2Aepsilon_(0))`
or `E=(3)/(2)(Q)/(cd)` or `Ed=(3Q)/(2C)=V`
ii. `F=E(-Q)=((2Q)/(2Aepsilon_(0)))xx((-Q))/(1)=(Q^(2))/(Aepsilon_(0))`
`=(Q^(2))/(Aepsilon_(0))` ltbgt iii. Energy `=(1)/(2)epsilon_(0)E^(2)Ad=(1)/(2)epsilon_(0)((3Q)/(2Cd))^(2)Ad=(9)/(8)(Q^(2))/(C)`

An object kept on the principle axis is moving in the sme directions as that of mirror as shown in the figure. Speed of object and mirror is `10(m)/(s)` and `(40)/(13)(m)/(s)`. Radius of the curvature of the mirror is 20 cm. If the distance of object from the mirror at this instant is 5x cm, velocity of image at this instant is found to be zero. Find x.

Answer» Correct Answer - 5
`vecV_(im)=-(v^(2))/(u^(2))vecv_(om)`
`0-(40)/(13)=-((-10)/(-10+x))^(2)(10-(40)/(13))`
`(-10)/(-10+x)=+-(2)/(3)`
`x=25,-5cm`
Object is infront of mirror
Hence `25cm`
