Homework Statement



(8x^2y^3-2y^4)dx+(5x^3y^2-8xy^3)dy=0


Homework Equations





The Attempt at a Solution



I've already tried the most logical steps. The equation isn't exact and I couldn't find an integrating factor to make it exact. It's also not homogeneous or separable. I have to be making an error somewhere. I've done all my other questions but this one is just killing me. Help please!

Did you get rid of the common factor of y^2 :$$\frac{dy}{dx}=\frac{2y^2-8x^2y}{5x^3-8xy}$$
... where does this come from?
