Answer
B) 3c(3ab+a+4ab)
Step-by-step explanation:
First find the common factor of (9abc+3ac+12bc) (the common factor is 3c because 3 is the greatest common factor of the coeffecients given and c is in all the terms of the variables given)
then, put 3c outside the parenthesis and factor the terms.
3c(3ab+a+4ab)
when you multiply 3c(3ab+a+4ab) you should get the polynomial that the question gave you. (9abc+3ac+12bc)
