Question 168594: 2ab+2ay+bx+xy
Answer by midwood_trail(310)   (Show Source):
You can put this solution on YOUR website! Yu did not state directions but I assume you want to factor, right?
2ab + 2ay + bx + xy
When you have 4 terms, it is best to factor by groups.
2ab + 2ay = group 1
bx + xy = group 2
Factor each group individually.
2ab + 2ay = 2a(b + y)
===============================
bx + xy = x(b + y)
We now have this:
2a(b + y)x(b + y)
Notice that we have two quantities that are the same, which is (b + y).
We only need one of them.
Your final answer is the following two factors:
(2a + x)(b + y)
