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))
Maple raw output
[y(x) = -1/3/x*3^(1/2)*(x*(-x^3+3*_C1))^(1/2), y(x) = 1/3/x*3^(1/2)*(x*(-x^3+3*_C1))^(1/2)]
