\[ \left \{ \left ( y \left ( x \right ) \right ) ^{2}+{\frac {{x}^{2}}{3}}-{\frac {{\it \_C1}}{x}}=0 \right \} \] Mathematica raw input
DSolve[x^2 + y[x]^2 + 2*x*y[x]*y'[x] == 0,y[x],x]
Mathematica raw output
{{y[x] -> -(Sqrt[-x^3 + 3*C[1]]/(Sqrt[3]*Sqrt[x]))}, {y[x] -> Sqrt[-x^3 + 3*C[1]]/(Sqrt[3]*Sqrt[x])}}
Maple raw input
dsolve(2*x*y(x)*diff(y(x),x)+x^2+y(x)^2 = 0, y(x),'implicit')
Maple raw output
y(x)^2+1/3*x^2-1/x*_C1 = 0
