You went to a lot of trouble to write this out. In the form of fractions is this what you meant?

+%28%2856x%5E3+%2B64x%5E2+-20x%29%2F%288x%5E2+-+2x+-15%29%29%2A%28%282x%5E2+%2B5x-21%29%2F%2863x%5E3%2B129x%5E2-42%29%29

Is that what you meant, or perhaps either you or I mis-copied something. At least I hope we mis-copied something, because I've looked at this, and it doesn't simplify. I see a couple of places it would factor (the first numerator and both denominators factor), but I don't see how it will simplify!!
