Nonhomogeneous 2nd order DE

  1. Oct 22, 2008 #1
    1. The problem statement, all variables and given/known data

    y'' + 9y = 2x2e3x + 5

    2. Relevant equations


    3. The attempt at a solution

    I think the complementary solution yc = c1cos(3x) + c2sin(3x).

    If not for that little +5 at the end of the right hand side, I'm pretty sure I could solve it. But I don't know how to include it in my solution.

    Try adding a constant to your specific solution.
