\[ \boxed { x{\frac {\rm d}{{\rm d}x}}y \left ( x \right ) +x \left ( y \left ( x \right ) \right ) ^{2}-y \left ( x \right ) =0} \]
Mathematica: cpu = 0.008001 (sec), leaf count = 18 \[ \left \{\left \{y(x)\to \frac {2 x}{2 c_1+x^2}\right \}\right \} \]
Maple: cpu = 0.016 (sec), leaf count = 16 \[ \left \{ y \left ( x \right ) =2\,{\frac {x}{{x}^{2}+2\,{\it \_C1}}} \right \} \]
