Explain why the expression #13x+10# cannot be factored?
There are no common factors between the two terms
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.
