Question

5. Verify that:
(i) 4 is a zero of the polynomial p(x) = x – 4.
​

Answer 1

Given: p(x) = x - 4

To verify: 4 is zero of polynomial p(x) = x - 4

Answer: Let x = 0

               Then, x - 4 = 0

                          x = 0 + 4

                          x = 4

                Hence, verified that 4 is the zero of polynomial p(x) = x - 4
