If α and β are the zeroes of the polynomial ax^2+bx+c find the value of α^2+β^2. if α and β are the zeros of the polynomial ax2 + bx + c find the value of α2 + β2. If alpha and beta are the zeros of the polynomial ax2+bx+c then evaluate alpha^2 + beta^2.

(a+b)²=a²+2ab+b²
a²+b²=(a+b) (a-b)
So why can't we say this?
(a+b)²=a²+b²
Which means
a²+2ab+b²=(a+b) (a-b)
So why there is a need of two different identity?
