Here we answer the question: "What two numbers multiply to 393 and add up to -394?"

The answer to your question is:

-393 and -1

Below we illustrate and prove that -393 and -1 multiply to 393 and add up to -394:

-393 × -1 = 393
-393 + -1 = -394

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

x² - 394x + 393 = 0

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

(x - 393 ) (x - 1)

To summarize, since -393 and -1 multiply to 393 and add up -394, you know that the following is true:

x² - 394x + 393 = (x - 393 ) (x - 1)
