Homework Statement
y'=(x^2 +xy-y)/((x^2(y)) -2x^2)[/B]
Homework Equations
The Attempt at a Solution
I know that really the only way to solve this one is to use an integrating factor, and make it into an exact equation. My DE teacher said that to make it into a exact equation you need to take the partial of P(x,y) with respect to y minus the partial of (x,y) with respect to x, all divided by Q(x,y). However, when I do this, I get a nasty equation: (x^2 +5x-1-2xy)/(x^2 -2x^2).
We were told that you can only find μ, the integrating factor, if we got an equation in terms of one variable. Where am I going wrong?[/B]
