Use the distributive property to factor the expression.

15x + 6

To factor the expression using the distributive property, we need to find a common factor of both terms.

Looking at the coefficients of the terms, the greatest common factor of 15 and 6 is 3.

Factoring out 3 from both terms, we get:

3(5x + 2)

So, the factored form of the expression 15x + 6 is 3(5x + 2).
