(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

∫(1+4x^{2})^{1/2}when x runs from 0 to 2.

The answer is 4.647

2. Relevant equations

3. The attempt at a solution

I tried u substitution, giving me

u = 1+4x^{2}

du = 8x

where 8 can be pulled out as a constant. But I still have x left over. I'm sure I'm doing something silly or forgetting something basic, cause I'm pretty sure this is suppose to come to me fairly easy, especially since school is almost over...
