Factor completely:
You should recognise this as the difference of two squares:

The difference of two squares is factorable as follows:

Applying this to your problem, the and the , so we have:

But we're not quite finished because you may also recognise that the two factors that we now have are the difference and the sum of two cubes, which are both factorable as follows:
and

So, applying this to the two factors we found from the difference of two squares, we get:
...and you could rearrange this a little:
The end!
