ANSWER
![(x + 2)(3x + 4)](https://tex.z-dn.net/?f=%28x%20%2B%202%29%283x%20%2B%204%29)
EXPLANATION
The given expression is
![3x(x + 2) + 4(x + 2)](https://tex.z-dn.net/?f=3x%28x%20%2B%202%29%20%2B%204%28x%20%2B%202%29)
We can see that (x+2) is the greatest common factor.
We factor to obtain;
![(x + 2)( 3x + 4)](https://tex.z-dn.net/?f=%28x%20%2B%202%29%28%203x%20%2B%204%29)
The correct choice is C.
