Question

If alpha, beta are zeroes of the quadratic polynomial p(x) = x^2 - (k - 6)x + (2k + 1). Find the value of k if alpha + beta = alpha * beta

Answer 1

here two zeroes are alpha and beta are given.

then, Alpha+ beta= -{-(k-6)}/ 1

= -(-k+ 6)= k-6

now,alpha* beta= 2k+1/1=2k+1

NOW,,ATQ.

=> 2k+1 = k-6

=> k= -7
