Primitive of Root of p x + q over Root of a x + b/Also presented as

Primitive of $\sqrt {\frac {p x + q} {a x + b} }$: Also presented as
This result can also be seen presented in this form:

$\ds \int \sqrt {\frac {p x + q} {a x + b} } \rd x = \frac {\sqrt {\paren {a x + b} \paren {p x + q} } } a - \frac {b p - a q} {2 a} \int \frac {\d x} {\sqrt {\paren {a x + b} \paren {p x + q} } }$
