First make a substitution and then use integration by parts to evaluate the integral

You need to use the substitution , such that:

Replacing the variable, yields:

You need to use the integration by parts such that:

You need to use the substitution , such that:

Replacing the variable, yields:

You need to use the integration by parts such that:

Replacing back the variable, yields:

Using the fundamental theorem of integration, yields:

Hence, evaluating the integral, using substitution, then integration by parts, yields
