well what you have is correct, but perhaps the computer system is really picky and they want it a certain way?

Maybe they want the answer as
\[\Large \frac{2x+h+2\sqrt{x(x+h)}}{h}\]
or maybe as
\[\Large \frac{2x+h+2\sqrt{x}\sqrt{x+h}}{h}\]
or maybe as
\[\Large \frac{x+h+2\sqrt{x}\sqrt{x+h}+x}{h}\]
