    What is the Inverse Laplace Transform of (2s^2 + 20s + 36) / (s^3 + 6s^2 + 9s)?

    Somehow I got from partial fraction 4 unknowns with 3 equations? A/s + B/(s+3) + (Cs+D) / (s+3)2

    What is the Inverse Laplace Transform of (2s^2 + 20s + 36) / (s^3 + 6s^2 + 9s)?

    Homework Statement F(s) = (2s2 + 20s + 36) / (s3 + 6s2 + 9s) Homework Equations L[e-at] = 1 / (s + a) L-1[(s+a) / ((s+a)2 + w2)] = e-atcos(wt) L-1[w / ((s+a)2 + w2)] = e-atsin(wt) The Attempt at a Solution Factored the top by 2 and the bottom by s, but the rest of the top seems...
