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:

-8 and 63

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

-8 × 63 = -504
-8 + 63 = 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 - 8 ) (x + 63)

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

x² + 55x - 504 = (x - 8 ) (x + 63)
