    int(sqrt(u+1)/sqrt(u^2),u)=int(u^(-1/2)+1/u, u)

    you did mean for that sqrt(x+3) to be in the numerator correct?

    I wasn't sure since there wasn't brackets around the whole denominator symbolizing it is the denominator

    If he then mean it to be in the denominator, he could use partial fractions after that substitution above
