What two numbers multiply to -24 and add to -5?
The two numbers that multiply to -24 and add to -5 are 3 and -8
How to determine the numbersFrom the question, we have the following parameters that can be used in our computation:
Product = -24
Sum = -5
Let the numbers be x and y
So, we have
xy = -24
x + y = -5
Let x be 3 and y be -8
So, we have
3 * -8 = -24
3 - 8 = 5
The above equations are true
Hence, the numbers are 3 and -8
