What two numbers multiply to 504 and add up to -90?

Here we answer the question: "What two numbers multiply to 504 and add up to -90?"

The answer to your question is:

-84 and -6

Below we illustrate and prove that -84 and -6 multiply to 504 and add up to -90:

-84 × -6 = 504
-84 + -6 = -90

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

x² - 90x + 504 = 0

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

(x - 84 ) (x - 6)

To summarize, since -84 and -6 multiply to 504 and add up -90, you know that the following is true:

x² - 90x + 504 = (x - 84 ) (x - 6)
