Question

verify whether the following are zeros of the polynomial, indicate agaisnt them p(x)=(x+1)(x-2),x=-1,2​

Answer 1

Answer:

To verify whether the following are the zeroes of the polynomial then we need to put the given value of x in the polynomial and the answer should be 0.

p(1)= (-1+1)(1-2)

     = 0*(-1) = 0

0=0

p(2)= (2+1)(2-2)

      =  3*0 = 0

0=0

Therefore, YES the zeroes of polynomial p(x) are -1,2
