Question

List all the pairs of integers with a product of 36. Then find the pair whose sum is -13

Answer 1

The pair -9, -4

Step-by-step explanation:

36, 1

18, 2

9, 4

6, 6

-36, -1

-18, -2

-9, -4

-6, -6

~~~~~~~~~~~~~~

36 + 1 = 37

18 + 2 = 20

9 + 4 = 13

6 + 6 = 12

-36 + -1 = -37

-18 + -2 = -20

-9 + -4 = -13

-6 + -6 = -12

Hope this helps :D

Answer 2

Answer: -9,-4

Explanation: I'll list them with a negative sign because we want the sum to be negative. both of the numbers should be negative because the product is positive.

-1×-36

-2×-13

-3×-12

-4×-9

-6×-6

it is clear that -4+-9=-13

hope this helped
