Answer: \frac{x}{2} \sqrt{x^{2}-9}-\frac{9}{2} \log \left|x+\sqrt{x^{2}-9}\right|+c

Given: \int \sqrt{x^{2}-9}dx

Solution:

\begin{aligned} &\int \sqrt{x^{2}-9} d x \\ &I=\int \sqrt{x^{2}-a^{2}} d x=\int \sqrt{x^{2}-3^{2}} d x \quad\left[\int \sqrt{x^{2}-a^{2}} d x=\frac{x}{2} \sqrt{x^{2}-a^{2}}-\frac{a^{2}}{2} \log \left|x+\sqrt{x^{2}-a^{2}}\right|+c\right] \end{aligned}

Given by

\therefore I=\frac{x}{2} \sqrt{x^{2}-9}-\frac{9}{2} \log \left|x+\sqrt{x^{2}-9}\right|+c
