Here we answer the question: "What two numbers multiply to -448 and add up to -48?"

The answer to your question is:

-56 and 8

Below we illustrate and prove that -56 and 8 multiply to -448 and add up to -48:

-56 × 8 = -448
-56 + 8 = -48

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

x² - 48x - 448 = 0

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

(x - 56 ) (x + 8)

To summarize, since -56 and 8 multiply to -448 and add up -48, you know that the following is true:

x² - 48x - 448 = (x - 56 ) (x + 8)
