Simple Trinomials
A simple trinomial is a mathematic expression with 3 terms of different meanings and values. The usual expression has x as the variable but any letter can be put in its place. As trinomials get more complicated there can be multiple answers, but as for now, simple trinomials have just one. The answer to a simple trinomial should be in a fraction form: e.g (x+5)(x+3).

I usually do the “tic tac toe” method but for now, I will try and make it simple.
We first start with seeing products of the 8. We need to find a set of products that add to the middle number(6x).
We have 8,1 and 4,2.
4 and 2 seem to add up to 6. This means all we have to do is just to factor them. Just put both in brackets accompanied with an x.
(x+4)(x+2)
