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

    ∫ √x/(1+√x)

    2. Relevant equations

    3. The attempt at a solution

    t=√x ; x=t^2 ; dx= 2t

    ∫ (2t^2)/(1+t)

    and now?

    Simplify your denominator with another substitution.

    Bring the 2 outside the integral and then add and subtract 1 in the numerator.

    Hi ddr,

    Perform polynomial algebraic division and integrate the result directly.
