Thanks, I know the product rule - my answer was the simplified version of what that but somewhere in my simplification I went wrong. How do I proceed from what you've posted? Or is that as far as we're supposed to go?

common denominator is $\displaystyle 2\sqrt{x+2}$ ... proceed from there.
you should get $\displaystyle \frac{5x^2 +8x - 9}{2\sqrt{x+2}}$
