1. Is the n^2 supposed to be an a^2 ?

If so, you can combine three pairs of terms. Otherwise, two pairs.

Just multiply each term in parentheses by 6 and combine "like" terms.

You may also able to factor, after that.

You should try this yourself instead of looking for a web site (including jiskha) to do it for you.
