Hello, puzzledwithpolynomials!
It helps if you write out the terms completely ... then simplify.

I am just having trouble with simplifying radicals within the binomial in conjunction w/ the bionomial thm. I understand how it works thus far and all of that...but these two problems (and the radicals) are messing me up.
1. (a-2sqrt(3))^6
2. (a-sqrt(2))^5
