Calculus - Simplifying equation (possible error)

I have a Calculus book with the following equation which is then simplified down but I think that there might be an error.

I have pointed out where I think the error is and what I think the correction should be.

Can anyone please confirm this for me. If I am wrong could you please tell me why.

Many thanks in advance.

Yes it should be $\displaystyle \frac{h(4+h)}{h}$.

Am I correct in assuming that $\displaystyle \displaystyle \begin{align*} f(x) = x^2 \end{align*}$?
