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