How do you factor trinomials? How can we check the binomial factors to verify that they are truly factors?

  • 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
