Because this is a second order equation, you will need two independent solutions to the homogeneous differential equation. Try putting y= v(x)/x into the differential equation. That reduces to a first order, separable equation so that you can find v and then another y solution.
and I need to find the complete general equation corresponding to
Can someone get me started with this.. do I differentiate y(x) part and substitute that into the equation?
After you you have done that, you can use those solution in variation of parameters.
