Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0
An example:
2(x + y) + 4 = (4x + 4y + 8)/2
2x + 2y + 4 = 2x + 2y + 4
0 = 0

In order to solve for the other binomial, it's a hit-and-miss game :) Kind of
We know that in order to get x^2 there has to be an x multiplied by an x
(x + 9) (x (+/-) __)
What multiplied by 9 equals - 36 but also when added to nine equals 5?
14:18 is an equivalent ratio!
