Simplifying Radical Expressions

Hi, I have a quick little problem that I should be able to understand,
but for some reason the solution is eluding me.

SQRT(3 + 2 * SQRT(2)) - SQRT(3 - 2 * SQRT(2))

I know that this expression simplifies to 2, but I cannot figure out
why. Any suggestions on how to approach this type of problem would be
most appreciated.
