Question

.If α and β are zeros of the quadratic polynomial f(x) = x² -px +q, then the value of α²+β² *


2q - p²

p² - 2q

-p² - 2q

none of these​

Answer 1

Step-by-step explanation:

alpha ²+Beta ²=(alpha+beta)²-2alpha *beta

alpha +beta =-a/b =1/p

aplha×beta =c/a=q

i.e.,=1/p²-2q

=1-2qp²/p² is the solution
