\[ \int \frac {16 x-16 e x}{-1+e^3+12 x-48 x^2+64 x^3+e^2 (-3+12 x)+e \left (3-24 x+48 x^2\right )} \, dx \]

Optimal antiderivative \[ 2-\frac {8}{\left (4-\frac {1-{\mathrm e}}{x}\right )^{2}} \]

command

integrate((-16*x*exp(1)+16*x)/(exp(1)^3+(12*x-3)*exp(1)^2+(48*x^2-24*x+3)*exp(1)+64*x^3-48*x^2+12*x-1),x, algorithm="giac")
