problem. What's the common thread or unit between

all four of these elements? Ahh well, there we've already given you a hint.
- 00:28
Yeah the number 4 part of it. What else?
- 00:31
X. Okay so there's a 4x common to all of these
- 00:36
and we can factor it out to make life oh so much simpler.
- 00:39
We now have an equation that looks like this: 4x times the quantity xy
- 00:44
plus 4y plus 3x plus 12 we have an equation here
- 00:48
a very common form. We can factor this down to the
- 00:52
quantity X plus 4 times the quantity y plus 3.
- 00:56
Here we go. So boom! The answer is B.
