I am lost on a couple problems, can anyone help. We are working on Partial Fraction Decomposition, and these are two problems I am stuck on.

Problem 1

x^2-2x / x^4+x^3+16x^2+9x+63

Problem 2

2 / x^4+4x^3+11x^2-3x+9

we were working on breaking down the denom, and using the A+B+C method to solve. Any help would be great.
