It seems to me that you are into "factoring" trinomials, which is basically a process of converting trinomials into binomial factors. Of course, not all trinomials can be factored, but "factoring trinomials" constitutes an entire lesson for those that can be factored.
Here's an elementary example:
Factor the following expression:

The factors will be two "binomials" of the following form:
You'll need to find the values of a and b. These two binomial factors, when multiplied together will result in the original trinomial expression.
Comparing the binomial factors with the trinomial, you can write this:
so this means that:
a+b = 3 and a*b = 2
What are the possibilities?
a = 1 and b = 2 or
a = 2 and b = 1
Let's try these in the binomial forms and see what we get.
Multiply these factors using the FOIL method.
Simplifying this, we get:
The original trinomial!

You would get exactly the same result if you used:
a = 2 and b = 1
