Question

(x^3y^2-y)dx+(x^2y^4-x)dy=0 solve using integrating factor

Answer 1

Integrating factor is not apparent

Answer 2

Please help

Answer 3

no idea ... sry

Answer 4

\[(x^3y^2-y)+(x^2y^4-x)dy/dx=0\]\[(x^3y^2-y)=\frac d {dx}\left(xy- \frac15x^2y^5\right)-y+\frac25xy^5\]


...no idea what i'm doing.... wolfram alpha doesn't show an elegant solution.
