Answer:
A is correct! 3(x+3)(x+9)
Step-by-step explanation:
Factor out 3
3(x^2+12x+27)
You can factor using X games, so basically it must add to the middle term's number (12) and multiply to whatever the first and 3rd term's numbers are (1 times 27)
so
12
(?) x (?)
27
Solve for the question marks, which is 3 and 9
3(x+3)(x+9)
Hope this helps! Please mark brainliest :)
