You express

Now your expression becomes

You can express

Now you have a sum of two cubes, which you can factor according to the formula

So, your expression will become

This polynomial can be seen as a sum of cubes.

Remember the rule of factorize a sum of cubes:

generally the second factor can't be further factored, but this happens *only* if it is a square polynomial, but... this is a 4th degree polynomial, so:

and they can't be further factored.

Finally:

Factors are: x +
