I feel dumb because I can't see how you get from this:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]x \frac{dy}{dx}+x^2y+y=0[/tex]

to this

[tex]\frac{dy}{dx}+(x+\frac{1}{x})y=0[/tex]

this is what I would of thought it would be...

[tex]\frac{dy}{dx}+(x+\frac{y}{x})+\frac{y}{x}=0[/tex]

no?
