(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Solve (x^2 + y^2 - y)dx + x dy = 0 when x > 0, y > 0.

2. Relevant equations

(x^2 + y^2 - y)dx + x dy = 0

3. The attempt at a solution

dy/dx = - (x^2 + y^2 - y) / x

That seems like a tricky one. Can I make it a second-order diff. eq.?

Well, with the topic we have had about vectorfields I can backwards engineer it into

F(x,y) = (x^2 + y^2 - y)i+ (-x)j

But that dosn't make much sense to me.
