$$\int \frac{1}{x \sqrt{x + 2}}\, dx = C + \begin{cases} - \sqrt{2} \operatorname{acoth}{\left(\frac{\sqrt{2} \sqrt{x + 2}}{2} \right)} & \text{for}\: \frac{\left|{x + 2}\right|}{2} > 1 \\- \sqrt{2} \operatorname{atanh}{\left(\frac{\sqrt{2} \sqrt{x + 2}}{2} \right)} & \text{otherwise} \end{cases}$$
