    I have no idea how to approach this:

    integrate with respect to y

    y(y-8)/ (y-4)^2

    let u= y-4

    Have you tried rearranging the given substitution?

    i.e. y = u + 4

    whats the answer?
    The answer is y^2-8y+32/ y-4 + c


    So far I have
    u=y-4

    so u+4= y

    u-4= y-8

    therefore

    Im integrating with respect to y

    (u+4)(u-4)/ u^2
