Question

if alpha and beta are zeroes of the polynomial 2x2+7x+5 , then find the value of 1/alpha+1/beta​

Answer 1

Answer:

2x² + 7x +5

Step-by-step explanation:

as we know 1/alpha+1/beta​= (alpha+beta​) / alpha*beta

              (alpha+beta = sum of roots = -b/a = -7/2

             alpha*beta =product = c/a = 5/2

   hence answer = -7/2
