Check whether -2 and 2 are zeroes of polynomial x4 - 16​

Answer»

Answer:

They are the zeros

Step-by-step EXPLANATION:

f(x) = x^4 - 16

We KNOW 2^4 = 16

==> f(2) = 2^4 - 16

            = 16 - 16

            = 0

==> f(-2) = (-2)^4 - 16

             = 16 - 16                (POWER of negative numbers is positive)

             = 0
