    [SOLVED] Integral Confused!!!

    I have this question: [(1/t^2)+t].
    This is my working out.
    =(t^-2) + (t)
    =(t^-1/-1) + (t^2/2) + C
    =-t^-1 + (t^2/2) + C
    =-(1/t) + (t^2/2) + C
    But the answer I have says (t^2/2) - (1/t) + C
    Can some one please check if I have done something wrong.
    Thanks

    you're correct!
