Find the quadratic polynomial whose zeros are 2+√3 and 2-√3. |
|
Answer» X^2-4x+1 Sum of zero is 2+√3Product of zero is 2-√3X^2+(2+√3)x+(2-√3)X^2+2+√3x+2-√3 Let one zero be alpha and other be beeta.Alpha=2+√3 and beeta=2-√3. Sum of zero= Alpha+ beeta. 2+√3+2-√3=4...Product of zero= alpha× beeta= 2+√3×2-√3= (2)²-(√3)²= 4-3=1. X²- sum of zero(x)+ product of zeroX²- 4x+1. |

Prove that root 5is irrational |
| Answer» Let √5 be rational such that √5=p/q where p nd q are co prime numbers. Now;√5=p/q. q√5=p . Squaring both sides; 5q^2=p^2. .......(1) also;p =5s for some integer s;putting p=5s in (1) 5q^2=(5s)^2. 5q^2=25s^2. From (1) nd(2) weconclude that 5is a common factor of p^2as well as p nd q^2as well as q.Hence;our assumption that p nd q are co prime integers is wrong.therefore √5is irrational by contradiction. Hope it will help u. | |

Porperty of cyclic quadrilateral |
| Answer» Cyclic Quadrilateral Properties\tIn a cyclic quadrilateral, the sum of a pair of opposite angles is 1800. (supplementary).If the sum of two opposite angles are supplementary then it’s a cyclic quadrilateral.The area of a cyclic quadrilateral is [s(s-a)(s-b)(s-c)(s-c)]0.5 where a, b, c, and d are the four sides of the quadrilateral and the perimeter is 2s.The four vertices of a cyclic quadrilateral lie on the circumference of the circle.To get a rectangle or a parallelogram, just join the midpoints of the four sides in order.If PQRS is a cyclic quadrilateral, then ∠SAR = ∠SQR, ∠QPR = ∠QSR, ∠PQS = ∠PRS, ∠QRP = ∠QSP.If T is the point of intersection of the two diagonals, PT X TR = QT X TSThe exterior angle formed if any one side of the cyclic quadrilateral is produced is equal to the interior angle opposite to it.In a given cyclic quadrilateral, d1 / d2 \xa0= sum of the product of sides, which shares the diagonals endpoints.If it is cyclic quadrilateral then the perpendicular bisectors will be concurrent compulsorily.\t | |

prove that7+3√2 is not a rational number |
| Answer» Let 7+3√2 is arational number where 7+3√2=p/q and p and q are coprime numbers. 7+3√2=p/q. 3√2=p/q-7. √2=p-7q/3q. It shows that √2 is rational but we know that √2 is irrational.Hence our assumption is wrong by contradiction. | |

Prove that root 5 is a irrational |
|
Answer» Let✓5 be rationalWhose simplest form is a/b So, ✓5=a/b So, 5=a^2/b^2So, a^2=5b^2Here,5b^2 is divisible by 5 So, a^2is also divisible by 5 So,5is a factor of aNow, let\'s a=5cSo, ( 5c)^2=5b^2 25c^2=5b^2 5c^2=b^2Her,5c^2is divisible by 5So,b^2is also divisible by 5So,b is common factor for a And bSo our supposison is wrongHence✓5is irrational.
