Hi!
In order to solve this, we need 'un factor' the factorization.
Given:

Use the FOIL (Front, Outer, Inner, Last) distribution method:

Combine like terms:

Therefore, -3 is your answer.
(Hint: notice that, if you wanted to shorten this step, you can simply look at the last two terms in each of the parentheses and multiply them. In this case, it's 3 and -1, and when multiplied that's -3 ~ we got the same answer from before!)
