from the original problem it's a trinomial square, so that factors to (a^21)(a^21) hence a^4  a^2  a^2 + 1. Remember FOIL.
Those two are a difference of squares so you get (a+1)(a1)(a+1)(a1)
Pretty easy once you get used to it.

Yes i tested into college algebra and we spent 23 week on all kinds of factoring problems.(sum of cubes, differences of square, sum of squares of 2 consecutive integers, Quadratic Equations, Binomials and trinomials, few other don't remember all of them )Also sorry i did not post the answer to the problem, but the correct way is what Dlew has posted. Nice job on the math test btw.
