### Example Question #91 : How To Find Integral Expressions

Evaluate the following indefinite integral:

**Possible Answers:**

**Correct answer:**

To solve this problem we have to use a u substitution. A "u-sub" is done by using the following steps:

1. Set u equal to the x equation in parentheses, take the derivative, and solve:

2. Replace x values with u values and integrate accordingly:

3. Put the original x equation back in for u and add "C":
