 P: 28 Hi, I'm not exactly sure how to solve the following non-homogeneous ODE by variation of parameters. Solve the given non-homogeneous ODE by the variation of parameters: x^2y" + xy' -1/4y = 3/x + 3x Can someone please point me in the right direction? Help will be much appreciated!! -Sabrina

First you solve the homogeneous equation for two independent solutions ##y_1## and ##y_2##. Have you done that?
