Question

if alpha and beeta are the zeroes of quadratic polynomial p(x)=4x²-5x-1.find the value of  alpha^2betta+alpha beeta^2

Answer 1

The following solution is the same just replace alpha by p and beeta by q !!

Given that:

p and q are the zeros of polynomial f (x) = 4x ² – 5x – 1,

To find: p ² q + pq ² = pq (p + q)

Since, p and q are the zeros of polynomial f (x) = 4x ² – 5x – 1
