I have an implicit differential equation;(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\left(x^2+y^2\right)^2=x^2-y^2[/tex]

With a little work;

[tex]y' = -\frac{x\left(2x^2+2y^2-1\right)}{y\left(2y^2+2x^2+1\right)}[/tex]

Now I have to find the 4 points where y' = 0, how can I do that ?
