Answer 1

Please anybody help! :(

Answer 2

Set the function = 0 and solve for x

Answer 3

Did you try that?

Answer 4

Yes, I got (x^8-64)

Answer 5

is it correct until here?

Answer 6

No, When you cube a binomial, you must multiply the binomial by itself and multiply that answer by the binomial again.

Answer 7

A better approach would be to take the cube root of both sides.

Answer 8

Oh ok, I am sorry
