[tex]\int \sqrt{t^2+9}[/tex]

2. Relevant equations

3. The attempt at a solution

Apparently you can't solve this equation as you would [tex]\int \sqrt{t+9}[/tex], which would come out to [tex]\frac{2(t+9)^3/2 }{3}[/tex].

Instead, my calculator is getting this extremely complicated answer involving ln functions, and therefore I don't know how to integrate this.

I know I'm not giving much to go on as far as an attempt on a solution is concerned, but I really don't have a definite way to begin, and I need to know how to evaluate this.
