FACTORING NO Leading Coefficient Trinomials x2 + bx + c = (x + ?) (x + ?) Step #1: Find the factor pair (n1 and n2) that . MULTIPLY = c (outside) and . ADD = b (middle). Step #2: Split the middle term bx = n1x + n2x. Step #3: Perform factor by grouping on . x2 + n1x + n2x + c = (x + ?) (x + ?) Exp 1: Factor x2 + 6x + 8. Step #1: 2 • 4 = 8, 2 ... ................
