Ok, let's see if we can unravel the loop that you've ben thrown for.
First, you will need to learn to recognise cubic terms.
and
Rewrite your expression:
Once you see this, then you'll that your polynomial expression is the "difference of two cubes" for which there is a factored form, which, in general, looks like:
Thus, with no further ado, we can proceed from here.
Simplify.
