\[ y'(x)=\frac {\left (x y(x)^2+1\right )^3}{x^4 y(x) \left (x y(x)^2+x+1\right )} \] Mathematica : cpu = 1.28116 (sec), leaf count = 85

\[\text {Solve}\left [5 \left (c_1+\frac {1}{x}\right )+2 \log \left (x y(x)^2-x+1\right )+\tan ^{-1}\left (2 x y(x)^4+2 (x+1) y(x)^2+x+1\right )=\log \left (2 x^2 y(x)^4+x^2+2 x (x+2) y(x)^2+2 x+2\right )+\tan ^{-1}\left (2 y(x)^2+1\right ),y(x)\right ]\]
