What multiplies to get 14 and adds to get - 9

Hi. I begin by finding the positive factors of 14. They are: 1 x 14 and 2 x 7. None of those can be added to yield a negative number, so let's now instead consider their negatives: - 1 x - 14 and - 2 x - 7. Does either of these pairs, when added, yield - 9? Yes: - 2 and - 7.

To be clear: - 2 x - 7 = 14; and - 2 + - 7 = - 9.

So the answer is - 2 and - 7.
