    I am not sure about the particular solution, but did you get a homogeneous equation with \[\lambda=1,2\]? I will see if I can figure out a particular solution for the damping.

    or I may be off line entirely. We have not covered the variation of parameters method in detail.

    i have no problem using method of undetermined coefficients to solve this one... but somewhere I keep making mistake when I use variation... the answer should contain e^(x) and e^(2x) by the way - initial problem should have e^(-x), not e(-x)... sorry

    I read it that way, but I don't think I'm going to be any help on this one, sorry. We haven't covered variation of parameters enough. Hopefully someone else will be able to help you out.
