\[ \int \frac {(a g+b g x) \left (A+B \log \left (\frac {e (a+b x)}{c+d x}\right )\right )}{c i+d i x} \, dx \]

Optimal antiderivative \[ \frac {g \left (b x +a \right ) \left (A +B \ln \left (\frac {e \left (b x +a \right )}{d x +c}\right )\right )}{d i}+\frac {\left (-a d +b c \right ) g \ln \left (\frac {-a d +b c}{b \left (d x +c \right )}\right ) \left (A +B +B \ln \left (\frac {e \left (b x +a \right )}{d x +c}\right )\right )}{d^{2} i}+\frac {B \left (-a d +b c \right ) g \polylog \left (2, \frac {d \left (b x +a \right )}{b \left (d x +c \right )}\right )}{d^{2} i} \]
