Question

find the value of k if of the polynomial x square - (K+ 6 )X +( 2 k - 1 )has sum of its zeros half of their product ​

Answer 1

K=7

EQUATION WAS WRONG EQUATION IS:-

X^2-(K+6)X+2(2K-1)=0

SOLUTION:-

◆ Given,

2(α+β)=αβ

◆ α+β = -b/a = - ( - { k+6 } )/1

◆ αβ = c/a = 2(2K-1)/1

● 2(α+β) = αβ

● 2(K+6) = 4K -2

● 2K + 12 + 2 = 4K

● 2K = 14

● K = 7

Answer 2

Answer:Answer is 7...................
