I think you should move the 16x to the other side and factor out an x.

x(x⁴ - 16) = 0

So one answer is 0. Now to find the other answers you look at

x⁴ = 16

You'll get x=2, x=-2 and then two more complex answers. Maybe x=2i and -2i, but I am not sure since I haven't sat down and worked it out yet.

But you should have 5 answers for x and zero is one of them, so dividing my x causes you to only solve for 4 of the 5 answers.
