Simple trinomial
What's a trinomial?
A trinomial is an expression which has 3 terms. There are 2 types:
Simple trinomial
A simple trinomial only has a coefficient of 1. So it always starts with an x^2
When you factor, your answer would always be like this

Introduction
Complex trinomial
Add to 11
Multiply to 24.
1 x 24
2 x 12
3 x 8
4 x 6
You need to find the factors of 24, which also add up to 11.
When you factor you nedd ( ) ( )
The factors of 24 which multiply with 24 and add to 11 are 3 and 8.
Example 1:
Example 2:
Multiply to 12.
1 x 12
2 x 6
3 x 4
Multiply to 12.
-1 x (-12)
-2 x (-6)
-3 x (-4)
I did this instead of the other one because the middle term is a negative. So the factors of 24 have to add to (-7). When you multiply a negative and a negative you get a positive. Also, when you add a negative and negative you get a positive.
The factor of 24 also, has to add up to (-7)
The factors of 12 which multiply with 12 and add to (-7) are (-3) and (-4).
