\[ y'(x)=\frac {(y(x)+1) (2 y(x)+1)}{x \left (2 x y(x)^4+x y(x)^3-2 y(x)-2\right )} \] Mathematica : cpu = 0.582033 (sec), leaf count = 56

DSolve[Derivative[1][y][x] == ((1 + y[x])*(1 + 2*y[x]))/(x*(-2 - 2*y[x] + x*y[x]^3 + 2*x*y[x]^4)),y[x],x]
 

\[\text {Solve}\left [-\frac {1}{8} y(x)^2+\frac {3 y(x)}{8}-\frac {1}{2 x (2 y(x)+1)}-\frac {1}{2} \log (y(x)+1)+\frac {1}{16} \log (2 y(x)+1)=c_1,y(x)\right ]\] Maple : cpu = 0.267 (sec), leaf count = 54

dsolve(diff(y(x),x) = 1/x*(1+2*y(x))*(1+y(x))/(-2*y(x)-2+x*y(x)^3+2*x*y(x)^4),y(x))
