Why not? You've had plenty of help with "simplifying with exponents" and "factoring polynomials" sort of exercises. Are you just copying solutions into your homework, instead of learning...? I certainly hope not.

Please attempt the exercise, and then, if you get stuck, please reply showing what you have tried and how far you have gotten. Thank you.
