I'm having trouble solving this differential equation:

(2x^2)yy' = −1

I'm just really not sure how to go about solving this.

Why isn't it separable?

[tex]2x^2 y \frac{dy}{dx} = -1 \Rightarrow 2y dy = -\frac{dx}{x^2}[/tex]

Ah yes, that's actually quite easy, I'm just being dense.

Thanks for the help.
