    All you have to do is some minor algebra.


    VdV/(kV+g) =  \frac{(1/k) (kV +g)- g/k}{kV+g}

    Seperate the fraction we get.

     \frac{1}{k} +\frac{- g}{k(kV+g)}

    Your integral reduces to

     \int \frac{1}{k} +\frac{- g}{k(kV+g)} dV

     \int \frac{1}{k}+\frac{- g}{k(kV+g)} dV =  \frac{V}{k} - \frac{ g  ln(kV +g)}{k^{2}}
