To find two factors of 80 that add up to -2, we need to look for pairs of numbers whose product is 80 and whose sum is -2. The factors that satisfy this condition are -10 and 8, since (-10) + 8 = -2 and (-10) * 8 = -80. Thus, the numbers -10 and 8 are the factors of 80 that add to -2.

It wasn't me, but I would have come up with 33. The four factors of 33 add up to 48.
-10 and +10.
The factors of 8 are 1, 2, 4, and 8. The factors that add up to 10 are 2 and 8.

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).
The 8 factors of 56 are 1, 2, 4, 7, 8, 14, 28, and 56. 2 and 8 add up to 10. Also, 1, 2, and 7 add up to 10.
