What two numbers multiply to -441 and add up to -56?

Here we answer the question: "What two numbers multiply to -441 and add up to -56?"

The answer to your question is:

-63 and 7

Below we illustrate and prove that -63 and 7 multiply to -441 and add up to -56:

-63 × 7 = -441
-63 + 7 = -56

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

x² - 56x - 441 = 0

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

(x - 63 ) (x + 7)

To summarize, since -63 and 7 multiply to -441 and add up -56, you know that the following is true:

x² - 56x - 441 = (x - 63 ) (x + 7)
