A student is attempting to factor a polynomial. Sample mathematical work is shown below. Which statement best applies to the sample mathematical work?

Given 3x + 6, the factors of the first term are 3 and x, and the factors of the second term are 1, 2, 3, and 6. Thus, the greatest common factor is 3. Dividing through by the greatest common factor, I get x + 3. Thus, the factored polynomial is 3(x + 3).
