Find the general solution of this differential equation, given that a solution of the corresponding homogeneous equation is y = x,

(x^2)y'' + x(x-2)y' - (x-2)y = x^3

I can sorta deal with these problems but i havnt came across them with functions of x attached to the y's, I can also deal with them in the case of y'' + y' + y = f(x) :s... do i still find an auxillary equation or what? Can someone show me how these type of questions are done please? Thanks
