DSolve[x*y''[x] == y'[x] + y'[x]^3,y[x],x]
Mathematica raw output
{{y[x] -> ((-I)*Sqrt[-1 + E^(2*C[1])*x^2])/E^C[1] + C[2]}, {y[x] -> (I*Sqrt[-1 + E^(2*C[1])*x^2])/E^C[1] + C[2]}}
Maple raw input
dsolve(x*diff(diff(y(x),x),x) = diff(y(x),x)^3+diff(y(x),x), y(x))
Maple raw output
[y(x) = -(-x^2+_C1)^(1/2)+_C2, y(x) = (-x^2+_C1)^(1/2)+_C2]
