Question

ii) Verify whether x=-1 and 2 are the zeroes of the polynomial p(x) = (x+1) (x+2).

Please explain in step by step ​

Answer 1

Answer:

If x = −1 and x = 2 are zeroes of polynomial p(x) = (x +1) (x − 2), then p(−1) and p(2)should be 0. Therefore, x = −1 and x = 2 are zeroes of the given polynomial
