Formula For Factoring Trinomials (when a =1)

It's always easaier to understand a new concept by looking at a

specific example so you might want to do that first. This formula works

when 'a' is 1. [ In other words, we will use this approach whenever the

coefficient in from of x2 is 1.

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

Step-by-step explanation:
