    Fraction Integration

    I can't find a working solution to get to the integral of
    f(x)=\frac{2}{3}x+3
    Because the answer is given in the solutions as
    F(x)=\frac{1}{3}x^{2}+3x+c
    I can work backwards easily enough to see that it is correct.

    But without the solution I can't figure it out for myself.

    Can anybody explain to me how I would do this on my own?

    Many thanks.

    It's only the \frac{2}{3}x part I can't manage, the +3 is easy enough.

    It's Ok, I figured it out seconds after posting.

    Sorry about the pointless thread, I should have worked at it for longer before posting.
