Hi I'm really stuck with some homework:
Find the general solution of the differential equation,
$$(x+(1/x))\frac{dy}{dx} +2y = 2((x^2)+1)^2$$
So far, I've divided both sides by $x+(1/x)$ and integrated $2y/(x+(1/x))$ to get $y \ln((x^2)+1)$ but have no idea where to go from here.
Anyone know what I need to do next?
