Question

Check -2 and 2 are zeroes of the polynomial X4-16

Answer 1

Answer:

Step-by-step explan

So first, 4x-16=0

We have to substitute x for -2

4x-2  -16=0

-8  -16=0

-24=0

so -2 isnt the zero of the polynomial

so second, we substitute 2 for x

4x2 -16=0

8-16=0

-8=0

so -8 isnt the zero of the polynomial
