Answer:
-7 and -8
Step-by-step explanation:
1. First, let's find the factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
- This means that the negative factors of 56 are -1, -2, -4, -7, -8, -14, -28, -56
2. Now, let's combine these factors and see which one adds to -15!
- [tex]1 + 56 = 57[/tex]
- [tex]2 + 28 = 30[/tex]
- [tex]4 + 14 = 28[/tex]
- [tex]7 + 8 = 15[/tex]
- [tex]-1 - 56 = -57[/tex]
- [tex]-2 - 28 = -30[/tex]
- [tex]-4 - 14 = -28[/tex]
- [tex]-7 - 8 = -15[/tex]
3. Nice! Now that we found the two factors of 56 that add up to -15, the answer is -7 and -8.
