Factoring with Exponents

Question

(x^2-4) (x^2-4)

-----------------------= -------------------------- I am stuck at this point finishing the factoring? Help?

3x+2 / x^2 -2x +1) 3x+2/ (x-1)(x-1)

Thanks,

Brian

Answer 1

It looks like the only other factoring you can do in this problem is to factor the numerator as a difference of squares.

x² - 4 = (x - 2)(x + 2)
