Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have some equations I have derived though energy balances and have been using the Integration Factors method to solve equations in the form:

dy/dx + Py = Q

However, my original equations only work if I assume some variables to be constants. Removing this assumption leaves me with an equation of the following form:

dy/dx + (a+b.y^2)y = Q

I have no Idea how to solve this problem. I cannot find a method that works. Does anybody know how to integrate such a problem?

Thanks in advance
