Can you determine a GCF? Key Terms: Polynomial, Monomial, Binomial, Trinomial, FOIL, 4 Step Method, GCF, Factor
Examples
Example 1 Factor ac=-30b=-7 -10, = -7 1.Multiply the a and c terms 2.Define factor pairs and sums 3.Relace b term with factor pairs 4.Factor by grouping
Example 2 Factor ac=6b=7 1, = 7 1.Multiply the a and c terms 2.Define factor pairs and sums 3.Relace b term with factor pairs 4.Factor by grouping
Example 3 Factor ac= 30b=17 15, = 17
Example 4 Factor ac=72b=18 12, = 18
