What two numbers multiply to __ and add up to __?

1. Multiply - 15 add - 2

2. Multiply - 32 add - 4

3. multiply - 14 add - 5

4. Multiply - 24 add 5

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.
