Step-by-step explanation:

Answer 2

Arrange the factors of the product so that when added you get the sum:
1. The factors of 15 are 3 and 5 or 1 and 15. You are looking for the pair that is two apart, which are 3 and 5. Because they add up to be negative 2, 5 must be negative, so the two numbers you get are 3 and -5. The rest can be solved similarly:
2. (Out of 1 and 32, 2 and 16, and 4 and 8, only 4 and 8 works) -8+4=-4, -8*4=-32
3. (Out of 1 and 14, and 2 and 7, only 2 and 7 works) -7+2=-5, -7*2=-14
4. (Out of 1 and 24, 2 and 12, 3 and 8, and 4 and 6, only 3 and 8 works) -3+8=5, -3*8=-24.
