    Simplifying a function

    Can someone help with this? Like always, I get stuck with something that doesn't match the choices like \frac{\frac{2}{3+h}-\frac{2}{3}}{h}

    \frac{\frac{2}{3+h}-\frac{2}{3}}{h}

    \frac{1}{h}\left(\frac{2}{3+h} - \frac{2}{3}\right)

    common denominator ...

    \frac{1}{h}\left(\frac{6}{3(3+h)} - \frac{2(3+h)}{3(3+h)}\right)

    \frac{1}{h}\left(\frac{6 - 2(3+h)}{3(3+h)}\right)

    finish it ...
