For a pair of numbers, the answer is the complex conjugate pair: 12.5 ± 21.9943 i where i is the imaginary square root of -1.
-25
The numbers are: 9 + square root of 129 and 9 - square root of 129
Considering only natural numbers, besides the obvious 1 x 671, the only combination of two numbers that multiplies into 671 is 11 x 61 (or 61 x 11, of course).
The numbers that add to get 6 and multiply to get 81 are 3 and 3.
