Optimal result

Integrand size = 22, antiderivative size = 206 \[ \int x (c+d x)^{-2-2 p} \left (a+b x^2\right )^p \, dx=\frac {(c+d x)^{-2 (1+p)} \left (a+b x^2\right )^{1+p}}{2 b (1+p)}-\frac {(c+d x)^{-2 (1+p)} \left (a+b x^2\right )^{1+p} \left (1-\frac {c+d x}{c-\frac {\sqrt {-a} d}{\sqrt {b}}}\right )^{-1-p} \left (1-\frac {c+d x}{c+\frac {\sqrt {-a} d}{\sqrt {b}}}\right )^{-1-p} \operatorname {AppellF1}\left (-2 (1+p),-1-p,-1-p,-1-2 p,\frac {c+d x}{c-\frac {\sqrt {-a} d}{\sqrt {b}}},\frac {c+d x}{c+\frac {\sqrt {-a} d}{\sqrt {b}}}\right )}{2 b (1+p)} \] Output:
