\[ \left \{ y \left ( x \right ) ={\frac {{\it \_C1}\,x}{ \left ( 1+x \right ) ^{3}}} \right \} \] Mathematica raw input
DSolve[x*(1 + x)*y'[x] == (1 - 2*x)*y[x],y[x],x]
Mathematica raw output
{{y[x] -> (x*C[1])/(1 + x)^3}}
Maple raw input
dsolve(x*(1+x)*diff(y(x),x) = (1-2*x)*y(x), y(x),'implicit')
Maple raw output
y(x) = _C1/(1+x)^3*x
