y''-2y'+y=6/(x^3)*e^x(adsbygoogle = window.adsbygoogle || []).push({});

the sollution to the homogenous equation is e^x and x*e^x, so how do I solve for the particual sollutioin, how do I choose the undetermined coefficients? I have tried:

(c + c1/x+c2/x^2+c3/x^4)*e^x and (cx^2+c1x+c2+c3/x), but none of them seems to give a good answer, should one of these work?

Maybe this should be in the homework section, but school hasn't started yet, so this isn't really homework. :P
