\[[y \left (x \right ) = {\mathrm e}^{\textit {\_C1} \,{\mathrm e}^{x}} \textit {\_C2}]\] Mathematica raw input
DSolve[y[x]*y''[x] == y[x]*y'[x] + y'[x]^2,y[x],x]
Mathematica raw output
{{y[x] -> E^(E^x*C[1])*C[2]}}
Maple raw input
dsolve(y(x)*diff(diff(y(x),x),x) = diff(y(x),x)^2+y(x)*diff(y(x),x), y(x))
Maple raw output
[y(x) = exp(_C1*exp(x))*_C2]
