Homework Help: Integration with square roots HELP!

  1. Dec 1, 2011 #1
    1. The problem statement, all variables and given/known data


    2. Relevant equations

    3. The attempt at a solution

    I tried using substitution but it clearly doesn't work because nothing in the brackets equals when derived.

    Anyone help me with the beginning steps?

    Substitute u=8x+1. I don't understand what your problem with that would be.
