Math Help - Need help on simplifying

1. Need help on simplifying

Use rationalization to simplify the given expression:

9t^2
--------------------
t + 2 - 2sqrt(t + 1)

I haven't got the slightest idea on how to approach this problem. Any help is appreciated!

2. Its a nasty looking thing but the hint is saying to use rationalization (i'm guessing in the denominator). Try $\displaystyle \frac{9t^2}{t+2-2\sqrt{t+1}} \times \frac{t+2+2\sqrt{t+1}}{t+2+2\sqrt{t+1}}$
