Question

If alpha and beta are the zeroes of polynomial ax2+bx2+c, then the value of alpha2 + beta 2 is

Answer 1

well,
alpha2 + beta2 + 2alpha.beta - 2alpha.beta

(alpha+beta)2 - 2alpha.beta....

also we know,

alpha+beta = -b/a
alpha.beta= c/a

Substitute values to get answer.


Hope you get your answer.
