Question

I’m thinking of 2 numbers

The product of these 2 numbers is -28

What could these numbers possibly be? List the possibility’s

The same 2 numbers have a sum of 3

What MUST these 2 numbers be?

Answer 1

It’s quite simple, the two numbers are 7 and -4.

Answer 2

Answer:

7, -4

Step-by-step explanation:

If the two numbers multiply to -28, their absolute value must both be less than 28. The numbers must also multiply into 28, meaning that the have to have a 7 and two 2s between them. This means that the numbers could be -7 and 4, 7 and -4, -14 and 2, 14 and -2, -28 and 1, or 28 and -1. The only set of these that add to 3 is 7 and -4.
