This week in pre-calc we learned how to factor using trinomials.

There are a couple steps to figuring this out, but once you have figured it out it is very simple.

- identify a,b, and c in the trinomial ax
^{2}+bx+c. - write down all factor pairs of c.
- identify which factor pair from the previous step sums up to b.
- Substitute factor pairs into two binomials.
