There are no common factors between the two terms

#### Explanation:

First, we can try factoring the constants in each term:

13 is a prime number and therefore can only be factored to 1 and 13.

10 can be factored as (1 x 10) or (2 x 5).

Because there are no common factors other than

And, because there is no

Therefore this expression cannot be factored.
