Question

question 2 of 5. select the correct answer. factor completely. 12x² + 28x

Explanation:

Step1: Find GCF of coefficients

The coefficients are 12 and 28. The GCF of 12 and 28 is 4.

Step2: Find GCF of variables

For the variable part, we have $x^{2}$ and $x$. The GCF of $x^{2}$ and $x$ is $x$.

Step3: Factor out GCF

Factor out 4x from $12x^{2}+28x$. We get $4x(3x + 7)$.

Answer:

D. $4x(3x + 7)$
