(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

y''-2ay'+a^2y=e^ax

Find a general solution

2. The attempt at a solution

I've found the general solution of the homogeneous eq: Ce^ax+Dxe^ax

Next, I must find a particular solution on the form Be^ax (*), right?

The derivative of (*) is Bae^ax and the 2nd derivative is B(a^2)e^ax

so that

y''-2ay'+a^2y=0

e^ax can never be 0, so I must have made a mistake...
