How to put a big bracket under different parts of a equation so that I could write e.g. a text specific to that part in the equation?

For example :

f =  x^3 +  2
|___|  |__|
|     |
text 1  text 2

This question came from our site for professional and enthusiast programmers.

What you want is

f = \underbrace{x^3}_\textrm{text 1} + \underbrace{2}_\textrm{text 2}

You would find it out in the mathmode manual or symbols manual.

Please provide hyperlinks for the manuals. Not everybody may know where to find them. (I've added them for you.) Also you should consider providing more information. The poster may not know what to look for. –  Marc van Dongen Feb 17 '12 at 7:53
$f(x) = \underbrace{(x+2)^3}_\text{text 1} + \overbrace{(x-3)}^\text{text 2}$
Would you still use \text if you wanted to include math? e.g., instead of "text 1" I want to have something like $g(x)$. (Also, congrats on your 1000th answer. Awesome work!) –  Mike Wierzbicki Feb 17 '12 at 6:12
