They are: 21+6+2 = 29
-21 and -1
Multiples don't add. Addends add, like 13 + 14 + 15 = 42 but I suspect you want factors, specifically prime factors. 2 x 3 x 7 = 42
29, 11, 2
419
6 + 3 + 2 7 + 3 + 1
126 and -63 42 and 21 54 and 9
-49 and -7 -42 and -14 -28 and -28
Although negative numbers aren't usually considered factors, you can use -21, -3 and -2.
There are no two numbers that multiply to 42 and add up to 8. The pairs of factors of 42, such as (1, 42), (2, 21), (3, 14), and (6, 7), do not sum to 8. Therefore, it is not possible to find such numbers.

X2 + 19X - 42 = 0What two factors of - 42 add up to 19?(X - 2)(X + 21)----------------------FOIL and see the function reappear.X = 2X = - 21
42 = 20 + 22
