DSolve[x*y[x]*y''[x] == -((1 + y[x])*y'[x]) + 2*x*y'[x]^2,y[x],x]
Mathematica raw output
{{y[x] -> Tan[(Sqrt[C[1]]*(-C[2] + Log[x]))/Sqrt[2]]/(Sqrt[2]*Sqrt[C[1]])}}
Maple raw input
dsolve(x*y(x)*diff(diff(y(x),x),x) = 2*x*diff(y(x),x)^2-(1+y(x))*diff(y(x),x), y(x))
Maple raw output
[y(x) = _C1*tanh(1/2*(ln(x)-_C2)/_C1)]
