To factor 5????2 + 13???? + 6, we must find factors of 30 which add to be 13. We found the factors of 30 earlier: Factors of 30 130 = 30 1 + 30 = 31 215 = 30 2 + 15 = 17 310 = 30 3 + 10 = 13 56 = 30 5 + 6 = 11 4) Which pair of factors multiplies to be 30 and adds to be 13? Example 2: To factor 5????2 17???? + 6 we must find factors of 30 which add to be -17. The factors still must multiply to be positive 30 but they must add to be a negative number. To multiply to be a positive 30, both factors must have the same signs. When both factors are negative they will multiply to be positive but add to be negative. 5) Finish the chart then circle the pair of factors that meet our conditions, factors of 30 that add to be -17: Factors of 30 That add to be -17 (-1)(-30) = 30 (-1) + (-30) = -31 (-2)(-15) = 30 (-3)(-10) = 30 (-5)(-6) = 30
