     \displaystyle \int \frac{2u}{1+u} du = \int \frac{2(1+u)}{1+u} dx - \int \frac{2}{1+u} du .
    For these types I would recommend that you always try to split up the fraction.

    Although I would also always recomment the splitting trick, if it is not intuitive you can use a substitution x = u+1.

    How did you split that fraction in that way? Is there like a rule that I could follow because i have no idea how you came up with that :O
