What two numbers multiply to -120 and add to -2
USPshnik [31]

Hello!

To answer this question we need to find the factors of -120.

The total set (both negative and postive! ) are the following:

  • 1, -120
  • 2, -60
  • 3, -40
  • 4, -30
  • 5, -24
  • 6, -20
  • 8, -15
  • 10, -12
  • 12, -10
  • 15, -8
  • 20, -6
  • 24, -5
  • 30, -4
  • 40, -3
  • 60, -2
  • 120, -1

After looking over all of these factors, we can see that 10 · -12 is equal to not only -120, but when the multiplication sign is replace by addition, it is equal to -2!

Hope this helps.
