 P: 778 Since it is in the form $e^{ax}/x^k$ try using $Ae^{-3x}/x$
 P: 778 Non-homogenous differential Equation I usually always try the simplest first. This doesn't pertain to this question, but if $Ae^{ax}$ didn't work I would try $Axe^{ax}$, and if that didn't work I would try $Ax^2e^{ax}$. It can be rather tedious for some questions but eventually you start to notice patterns.
