Ezra-3 and -20
In order to multiple to a positive number and add to a negative one, both the numbers in question must be negative.
The factors of 60 are:
- 1, 60
- 2, 30
- 3, 20
- 4, 15
- 5, 12
- 6, 10
The third pair listed, 3 and 20, will add up to a positive 23. So all that remains is to make them both negative.
(-20) + (-3) = -23
(-20) * (-3) = 60

What adds to 7 and multiples to 294?
There are no two real numbers that do, but two complex numbers do: (3.5 + i 3.5 √23) and (3.5 - i 3.5 √23) If you want them to add to 7 and multiply to -294, then the two real numbers -14 and 21 work. Or if you want them to add to -7 and multiply to -294, then the two real numbers 14 and -21 work.
