What two numbers multiply to -504 and add up to -55?

Here we answer the question: "What two numbers multiply to -504 and add up to -55?"

The answer to your question is:

-63 and 8

Below we illustrate and prove that -63 and 8 multiply to -504 and add up to -55:

-63 × 8 = -504
-63 + 8 = -55

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

x² - 55x - 504 = 0

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

(x - 63 ) (x + 8)

To summarize, since -63 and 8 multiply to -504 and add up -55, you know that the following is true:

x² - 55x - 504 = (x - 63 ) (x + 8)
