Primitive of Root of a x squared plus b x plus c over x squared

Theorem
Let $a \in \R_{\ne 0}$.

Then:
 * $\ds \int \frac {\sqrt {a x^2 + b x + c} } {x^2} \rd x = \frac {-\sqrt {a x^2 + b x + c} } x + a \int \frac {\d x} {\sqrt {a x^2 + b x + c} } + \frac b 2 \int \frac {\d x} {x \sqrt {a x^2 + b x + c} }$
