What two numbers multiply to 391 and add up to -392?

Here we answer the question: "What two numbers multiply to 391 and add up to -392?"

The answer to your question is:

-391 and -1

Below we illustrate and prove that -391 and -1 multiply to 391 and add up to -392:

-391 × -1 = 391
-391 + -1 = -392

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

x² - 392x + 391 = 0

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

(x - 391 ) (x - 1)

To summarize, since -391 and -1 multiply to 391 and add up -392, you know that the following is true:

x² - 392x + 391 = (x - 391 ) (x - 1)
