Here we answer the question: "What two numbers multiply to 392 and add up to -63?"

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 -63:

-56 × -7 = 392
-56 + -7 = -63

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

x2 - 63x + 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 -63, you know that the following is true:

x2 - 63x + 392 = (x - 56 ) (x - 7)
