1. Answer:

   x^2 + 3x – 10

   Step-by-step explanation:

   alpha = 2 , beta = -5

   sum of zeroes = alpha + beta

   = 2 + (-5)

   = 2-5

   = -3

   product of zeroes = alpha*beta

   = 2*(-5)

   = -10

   substituting the values in the formula [x^2 – ( alpha + beta )x + alpha*beta ] we get

   [ x^2 – ( -3)x + (-10)]

   x^2 +3x – 10
