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.

1. identify a,b, and c in the trinomial ax²+bx+c.
2. write down all factor pairs of c.
3. identify which factor pair from the previous step sums up to b.
4. Substitute factor pairs into two binomials.
