In this problem, we need to factor a given binomial using two different techniques.
We are given

GCF Technique
The first technique we'll use is finding the greatest common factor of both terms. We'll look at each constant and variable separately.

Therefore, the overall GCF of the binomial is:

We can factor it from each term to get:

Difference of Squares
In the second technique, we are going to apply the difference of squares.

To get it into that form, we need to rewrite each term of the binomial as a square:

Now we can write it as

Using our rule, we get
