\[ \int \frac {(d+e x)^2}{\left (a^2+2 a b x+b^2 x^2\right )^{5/2}} \, dx \]

Optimal antiderivative \[ -\frac {\left (-a e +b d \right )^{2}}{4 b^{3} \left (b x +a \right )^{3} \sqrt {\left (b x +a \right )^{2}}}-\frac {2 e \left (-a e +b d \right )}{3 b^{3} \left (b x +a \right )^{2} \sqrt {\left (b x +a \right )^{2}}}-\frac {e^{2}}{2 b^{3} \left (b x +a \right ) \sqrt {\left (b x +a \right )^{2}}} \]
