Question

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).

A. The student identified the greatest common factor incorrectly.
B. The student incorrectly divided each term by the greatest common factor.
C. The student failed to simpli

Answer 1

The answer here is B. If you notice the initial binomial, you will see the second term is 6. However, when the student divides by 3, he leaves a 3 inside the binomial instead of 2.

Answer 2

so its b...??

Answer 3

Yes
