Here you can take the Ace and King from your hole cards and make two pair, Aces and Kings, for a best hand of A-A-K-K-9. There is a pair of Queens in your hole cards and a pair of Deuces on board, but you don't need to use these as your two pair are bigger.

In this example you have made trip Aces for a final hand of A-A-A-K-J. Note that your kickers are K-J and not K-Q. You are using the Ace and King as your two hole cards, and cannot use the Queen as well.
