The product of 3 integers is -24. the sum of the integers is -12. what are the three integers?

I don't know any orderly procedure to use to derive the solution.
I just started going through them until I found one that works.  So
all I can give you is the answer, which is never very helpful.  Sorry.

The integers are  -1,  -3, and  -8 .

 (-1) x (-3) x (-8)  =  (+3) x (-8)  =  -24

 (-1 -3 -8)  =  (-4 -8)  =  -12

Wasssip message me so i can
