Both terms have a

in common, so we can pull it out. The factored form will be

times whatever is left after pulling it out.
In the first term, we will have just 8 left since everything else in the term is factored out.
The second term has a

left. Notice that both of these terms no longer have a negative sign since the negative was factored out.
The answer is
