$\textsf{Evaluate the function}$
\begin{align*}\displaystyle
I_5&=\int \sqrt{\frac{x^2-4}{x}} \, dx
\end{align*}

ok, I thought this would be a simple U subst, but nothing looks convienent

W|A gives a non-elementary result.

I presume when $x=0$ it is undefined

Are you sure you did not mean $\int \frac{\sqrt{x^2-4}}{x}\,\mathrm{d}x$?
