# Second order nonlinear nonhomogeneous differential equation

Hello,

I am having a little trouble solving this equation:

$\frac{d^2y}{dx^2} + \frac{A}{y}(\frac{dy}{dx})^2 + \frac{B}{(y+C)^2} = D - Ex$

where A, B, C, D, and E are constants and, sadly, not related.

So far, I've found this

http://eqworld.ipmnet.ru/en/solutions/ode/ode0344.pdf

which would solve the first half of the equation. Is it possible to use a technique such as variation of parameters to solve the rest, or do I need a new approach entirely?

Many thanks in advance for any help on this!
