What two numbers multiply to get -40 and add up to get -3

Answer:

5 and -8

Step-by-step explanation:

First, list the set of pairs of numbers that multiply to give 40 (so "factors" of 40):

1  40

2  20

4  10

5  8

Now look at the pairs to see which has a difference of 3.

1 and 40 has a difference of 39

2 and 20 has a difference of 18

4 and 10 has a difference of 6

5 and 8 has a difference of 3

Now all we need to do is determine whether 5 or 8 will be negative (if they are both negative, the product will be positive, so only one needs to be negative to have a product of -40).

As we need a final result of -3,  the two numbers will be: 5 and -8 (as 5 + - 8 = -3)

Answer:

5 and -8

Step-by-step explanation:

First I listed all the factors of 40 : 1, 2, 4, 5, 8, 10, 20 and 40.

Then out of those, I just had to find a pair with a difference of 3.

Or in other words, when I subtracted one from the other I either got 3 or -3.

The only pair that worked out that way when subtracted was 5 and 8.

However, if we multiply 5 and 8 we get 40, not -40, so something was amiss. When we add them up we have to get -3, and that only worked out if it was -8 and 5, since -8 + 5 = -3.

Therefore, the two numbers are -8 and 5
