We learned that when a trinomial is in the form x2 + bx + c, the factors are found by identifying a pair of integer factors of c that have a sum of b and then using the factors to write binomials that have a product equal to the trinomial. We completed several factoring trinomial problems to understand when to use negative and positive constant values. We checked our factoring of quadratics by multiplying the two binomial factors whose product is equal to the trinomial.
