Question

If alpha and beta are the zeroes of the quadratic polynomial p(x)=x^2-(k+6)x+2(2k+1) , then find the value of k if alpha + beta = ( alpha*beta )/2 . Please make it fast .. Its Urgent !

Answer 1

Answer:

Answer is k=5

Step-by-step explanation:

Hope thus is useful to you

Answer 2

Hey

@ + $ = k+6

@$ = 4k+2

@ + $ = @$/2

2(@+$) = @$

2(k+6) = 4k + 2

2k + 12 = 4k + 2

4k - 2k = 12 - 2

2k = 10

k = 10/2

k = 5

Note :- consider @ as alpha and $ as beta
