DSolve[x*(2*x^3 + y[x])*y'[x] == (2*x^3 - y[x])*y[x],y[x],x]
Mathematica raw output
{{y[x] -> (2*x^4)/(-x + Sqrt[1 + 4*x^4*C[1]]/Sqrt[x^(-2)])}, {y[x] -> (-2*x^4)/(x + Sqrt[1 + 4*x^4*C[1]]/Sqrt[x^(-2)])}}
Maple raw input
dsolve(x*(2*x^3+y(x))*diff(y(x),x) = (2*x^3-y(x))*y(x), y(x),'implicit')
Maple raw output
ln(x)-_C1-1/4*ln((x^3+y(x))/x^3)+1/2*ln(y(x)/x^3) = 0
