#### Answer:

For polynomials like this one, you must find a number to factor out by grouping

#### Explanation:

The GCF (greatest common factor) of the first two is

You can make the two x- 2 into one.

If you distribute you'll get the same thing as at the beginning. Beware: this method only works if the two expressions are the same (x - 2 in your problem)

Example:

As you can see, we can't go further because we have
