What are the roots of this polynomial?

It quickly becomes clear that if x = 2, the first factor will equal zero, and thus the entire expression will equal zero. Similarly, if x = -2, the second factor will equal zero and thus so will the entire expression. So x = 2 and x = -2 are both zeroes, or roots, of this polynomial. But what about that last term?
