\[ \int \frac {120 x^2-120 x \log \left (\frac {x}{4}\right )+120 x \log ^2\left (\frac {x}{4}\right )}{4 x^2-4 x^3+x^4+\left (4 x-2 x^2\right ) \log ^2\left (\frac {x}{4}\right )+\log ^4\left (\frac {x}{4}\right )} \, dx \]

Optimal antiderivative \[ \frac {60 x}{\frac {\ln \left (\frac {x}{4}\right )^{2}}{x}-x +2} \]
