If 1 and -1 are zeroes of the polynomial p(x) = ax3 + x2 - 2x + b, find the values of a and b.

  • -2
a= -4 b= 1
  • -1
First of all @Himani Garg, your answer is wrong. The correct answer is a = 2, b = -1. I don't need the one word answer, even I can conclude that from Hit and Trial method; however, I need the appropriate working for this question.
