What two numbers multiply to -321 and add up to 104?

Here we answer the question: "What two numbers multiply to -321 and add up to 104?"

The answer to your question is:

-3 and 107

Below we illustrate and prove that -3 and 107 multiply to -321 and add up to 104:

-3 × 107 = -321
-3 + 107 = 104

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 104x - 321 = 0

If so, the solution to factor the quadratic equation above is:

(x - 3 ) (x + 107)

To summarize, since -3 and 107 multiply to -321 and add up 104, you know that the following is true:

x² + 104x - 321 = (x - 3 ) (x + 107)
