DSolve[y'[x] + x*y'[x]^2 == y[x],y[x],x]
Mathematica raw output
Solve[{x == (C[1] - K[1] + Log[K[1]])/(-1 + K[1])^2, K[1] + x*K[1]^2 == y[x]}, {y[x], K[1]}]
Maple raw input
dsolve(x*diff(y(x),x)^2+diff(y(x),x) = y(x), y(x))
Maple raw output
[y(x) = x*exp(2*RootOf(-x*exp(2*_Z)+2*x*exp(_Z)+_Z+_C1-x-exp(_Z)))+exp(RootOf(-x*exp(2*_Z)+2*x*exp(_Z)+_Z+_C1-x-exp(_Z)))]
