Question

if (alpha - beta) and (alpha + beta) are the zeroes of the quadratic polynomial p(x)=x2 - 14x + 33, then the value of alpha is

Answer 1

Step-by-step explanation:

We know that, the sum of zeroes of a quadratic polynomial = {-(coefficient of x)}/coefficient of x²

So, (α+β) + (α-β) = 14

=> 2α = 14

=> α = 7
