Here we answer the question: "What two numbers multiply to -392 and add up to -49?"

The answer to your question is:

-56 and 7

Below we illustrate and prove that -56 and 7 multiply to -392 and add up to -49:

-56 × 7 = -392
-56 + 7 = -49

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

x² - 49x - 392 = 0

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

(x - 56 ) (x + 7)

To summarize, since -56 and 7 multiply to -392 and add up -49, you know that the following is true:

x² - 49x - 392 = (x - 56 ) (x + 7)
