    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!

    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}}
