\[ \int \frac {-4 e^2+118098 x-16 x^2+e (-39366+16 x)}{e^2 x^3-4 e x^4+4 x^5} \, dx \]

Optimal antiderivative \[ \frac {\frac {19683}{{\mathrm e}-2 x}+\frac {x^{2}}{2}+2}{x^{2}} \]

command

integrate((-4*exp(1)^2+(16*x-39366)*exp(1)-16*x^2+118098*x)/(x^3*exp(1)^2-4*x^4*exp(1)+4*x^5),x, algorithm="giac")
