Answer:

factor 1 = x

factor 2 = x - 5

(factor 1)  *  (factor 2)  = 84

    (x)      *      (x - 5)     = 84

          x² - 5x              = 84

              x² - 5x - 84   = 0

             (x - 12) (x + 7)  = 0

x - 12 = 0    or     x + 7 = 0

 x = 12       or      x = -7

factor 2 = x - 5   = (12) - 5  = 7    or    (-7) - 5  =  -12

Answer: 12, 7     or    -7, -12
