If one of the zeroes of the cubic polynomial x3 + ax² + bx + c is -1, then the product of theother two zeroes is

Answer»

$\large\underline{\sf{Solution-}}$

Let assume that

$\red{\rm :\longmapsto\: \alpha , \beta , \gamma \: are \: zeroes \: of \: {x}^{3} +a{x}^{2} + bx + c}$

Then further given that

$\rm :\longmapsto\: \alpha = - 1$

Since, - 1 the zero of the POLYNOMIAL, it means

$\rm :\longmapsto\: {( - 1)}^{3} + a {( - 1)}^{2} + b( - 1) + c = 0$

$\rm :\longmapsto\: - 1+ a - b+ c = 0$

$\bf :\longmapsto\: c = - a + b + 1$

Now, we know that,

$\boxed{\red{\sf Product\ of\ the\ zeroes= - \: \frac{Constant}{coefficient\ of\ x^{3}}}}$

$\rm :\implies\: \alpha \beta \gamma = - \: \dfrac{c}{1}$

$\rm :\longmapsto\:( - 1) \beta \gamma = - c$

$\rm :\longmapsto\: \beta \gamma = c$

$\rm :\longmapsto\: \beta \gamma = - a + b + 1$

ADDITIONAL INFORMATION :-

For CUBIC polynomial

$\red{\rm :\longmapsto\: \alpha , \beta , \gamma \: are \: zeroes \: of \: a {x}^{3} + b {x}^{2} + cx + d, \: then}$

$\boxed{ \rm{ \alpha + \beta + \gamma = - \: \dfrac{b}{a} }}$

$\boxed{ \rm{ \alpha \beta + \beta \gamma + \gamma \alpha = \: \dfrac{c}{a} }}$

$\boxed{ \rm{ \alpha \beta \gamma = - \: \dfrac{d}{a} }}$

For quadratic polynomial,

$\red{\rm :\longmapsto\: \alpha , \beta \: are \: zeroes \: of \: a {x}^{2} + b {x} + c, \: then}$

$\boxed{ \rm{ \alpha + \beta = - \: \dfrac{b}{a}}}$

$\boxed{ \rm{ \alpha \beta = \: \dfrac{c}{a}}}$

Answer»

Concept :

Quadratic equations are of the form :

⠀⠀⠀⌬ ax² + bx + c = 0

where , a ≠ 0 and a, b, c are real numbers.

So now for the given questions we would simplify each one of them and see whether it can be simplified in the general form of quadratic equation.

‎

QUESTION (i) :

⠀⠀⠀⌬ $\sf\:x^{2}-2x=(-2) (3-x)$

‎

Solution :

$\sf\:x^{2}-2x=(-2) (3-x)$

$\sf\implies\:x^{2}-2x=(-6+2x)$

$\sf\implies\:x^{2}-2x=-6+2x$

$\sf\implies\:x^{2}-2x-2x=-6$

$\sf\implies\:x^{2}-4x=-6$

$\sf\implies\:x^{2}-4x+-6=0$

‎

$\sf\therefore\:It~is~a~quadratic~equation$

════════════════════════

Question (II) :

⠀⠀⠀⌬ $\sf\:(x-3) (2x+1) =x(x+5)$

‎

Solution :

$\sf\:(x-3) (2x+1) =x(x+5)$

$\sf\implies\:x(2x+1)-3(2x+1) =x(x+5)$

$\sf\implies\:2x^{2}+x-6x-3=x^{2}+5x$

$\sf\implies\:2x^{2}-5x-3=x^{2}+5x$

$\sf\implies\:2x^{2}-5x+5x-3=x^{2}$

$\sf\implies\:2x^{2}-\cancel{5x}+\cancel{5x}-3=x^{2}$

$\sf\implies\:2x^{2}-3=x^{2}$

$\sf\implies\:2x^{2}-x^{2}-3=0$

$\sf\implies\:x^{2}-3=0$

‎

$\sf\therefore\:It~is~a~quadratic~equation$

════════════════════════

Question (iii) :

‎

⠀⠀⠀⌬ $\sf\:(2x-1) (x-3) =(x+5) (x-1)$

‎

Solution :

$\sf\:(2x-1) (x-3) =(x+5) (x-1)$

$\sf\implies\:2x (x-3) -1(x-3) =x(x-1)+5(x-1)$

$\sf\implies\:2x^{2}-6x-x+3=x^{2}-x+5x-5$

$\sf\implies\:2x^{2}-7x+3=x^{2}+4x-5$

$\sf\implies\:2x^{2}-x^{2}-7x-4x+3+5=0$

$\sf\implies\:x^{2}-11x+8=0$

‎

$\sf\therefore\:It~is~a~quadratic~equation$

════════════════════════

Question (iv) :

⠀⠀⠀⌬ $\sf\:x^{2}+3x+1=(x-2) ^{2}$

‎

Solution :

$\sf\:x^{2}+3x+1=(x-2) ^{2}$

$\sf\implies\:x^{2}+3x+1=x^{2}-2 \times x \times 2 +(2)^{2}$

$\sf\implies\:x^{2}+3x+1=x^{2}-4x +4$

$\sf\implies\:x^{2}-x^{2}+3x+4x+1-4=0$

$\sf\implies\:\cancel{x^{2}}-\cancel{x^{2}}+3x+4x+1-4=0$

$\sf\implies\:3x+4x+1-4=0$

$\sf\implies\:7x+1-4=0$

$\sf\implies\:7x-3=0$

‎

$\sf\therefore\:It~is~not~a~quadratic~equation$

[ Since a = 0 ]

════════════════════════

Question (V) :

‎

⠀⠀⠀⌬ $\sf\:(x+2) ^{3}=2x(x^{2}-1)$

‎

Solution :

$\sf\:(x+2) ^{3}=2x(x^{2}-1)$

$\sf\implies\:x^{3}+(2)^{3}+(3 \times x \times 2)(x+2)=2x^{3}-2x$

$\sf\implies\:x^{3}+8+6x(x+2)=2x^{3}-2x$

$\sf\implies\:x^{3}+8+6x^{2}+12x=2x^{3}-2x$

$\sf\implies\:x^{3}-2x^{3}+8+6x^{2}+12x+2x=0$

$\sf\implies\:-x^{3}+8+6x^{2}+14x=0$

$\sf\implies\:-x^{3}+6x^{2}+14x+8=0$

‎

$\sf\therefore\:It~is~not~a~quadratic~equation$

[ Since , highest DEGREE of the equation is 3 ]

Answer:

68 is the correct answer

Step-by-step explanation:

Out of 100, 10 failed and 7 didn't appear in the exam. This means 100— 10— 7=83 PASSED altogether.

Now passed 80(SCIENCE)+71(Maths)=151

And 151-83=68 passed in Science and Maths both.

The NUMBER 68 is being COUNTED in both 80 and 71. Hence

80— 68=12 passed in Science only.

71— 68=3 passed in Maths only

Whereas 68 passed in both

Answer:

After the tank is TILTED, the volume of EMPTY space in the tank equals 1/2*60*60*40 = 72 litres.

After the tank is tilted, the volume of empty space in the tank equals 1/2*60*60*40 = 72 litres.This includes 32 litres of water which was collected.

After the tank is tilted, the volume of empty space in the tank equals 1/2*60*60*40 = 72 litres.This includes 32 litres of water which was collected.So, the volume of the empty space before was 40 litres.

After the tank is tilted, the volume of empty space in the tank equals 1/2*60*60*40 = 72 litres.This includes 32 litres of water which was collected.So, the volume of the empty space before was 40 litres.Hence, the height of the empty space was 40*1000/(40*60) = 16.66 CM
