problem. What's the common thread or unit between
all four of these elements? Ahh well, there we've already given you a hint.
Yeah the number 4 part of it. What else?
X. Okay so there's a 4x common to all of these
and we can factor it out to make life oh so much simpler.
We now have an equation that looks like this: 4x times the quantity xy
plus 4y plus 3x plus 12 we have an equation here
a very common form. We can factor this down to the
quantity X plus 4 times the quantity y plus 3.
Here we go. So boom! The answer is B.
