3.3.79.1 Optimal result

Integrand size = 30, antiderivative size = 86 \[ \int \frac {\text {arcsinh}(a+b x)^2}{\left (1+a^2+2 a b x+b^2 x^2\right )^{3/2}} \, dx=\frac {\text {arcsinh}(a+b x)^2}{b}+\frac {(a+b x) \text {arcsinh}(a+b x)^2}{b \sqrt {1+(a+b x)^2}}-\frac {2 \text {arcsinh}(a+b x) \log \left (1+e^{2 \text {arcsinh}(a+b x)}\right )}{b}-\frac {\operatorname {PolyLog}\left (2,-e^{2 \text {arcsinh}(a+b x)}\right )}{b} \]
