-14 and -14 Add them together to get -28 Multiply them to get 196
Factors multiply, like 1 x 11. Addends add, like 5 and 6.
The factors that multiply to 120 and add up to -8 are -12 and 10. This is because when you multiply -12 and 10, you get -120, and when you add them together, you get -8. Thus, the pair of factors you are looking for is (-12, 10).
