\[ \int \frac {x^2}{\left (a^2+2 a b x+b^2 x^2\right )^{3/2}} \, dx \]
Optimal antiderivative \[ \frac {2 a}{b^{3} \sqrt {\left (b x +a \right )^{2}}}-\frac {a^{2}}{2 b^{3} \left (b x +a \right ) \sqrt {\left (b x +a \right )^{2}}}+\frac {\left (b x +a \right ) \ln \left (b x +a \right )}{b^{3} \sqrt {\left (b x +a \right )^{2}}} \]
