    2. Relevant equations

    Given in class on material connected with undefined integral

    3. The attempt at a solution

    Use integration by partial fractions.

    The integrand is not a rational expression, so I don't see how this technique could work.

    A better approach, I believe, is to complete the square inside the radical, and then use a trig substitution.

    Hmmm, good point trig substitution would probably work.

    I finally done it with a little help from a friend :)
    which is arcsin√x +C
