**1. The problem statement, all variables and given/known data**

As I was reviewing some of my previuosly learned calculus I came across somthing that I had either forgoten how to do or was never taught. How do you take the integral of somthing like this

[tex]\int \sqrt{\frac{9}{4}x+1}[/tex]

I don't know how to start with this one. Do I use U substitution?
