What two numbers multiply to 539 and add up to -84?

Here we answer the question: "What two numbers multiply to 539 and add up to -84?"

The answer to your question is:

-77 and -7

Below we illustrate and prove that -77 and -7 multiply to 539 and add up to -84:

-77 × -7 = 539
-77 + -7 = -84

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

x² - 84x + 539 = 0

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

(x - 77 ) (x - 7)

To summarize, since -77 and -7 multiply to 539 and add up -84, you know that the following is true:

x² - 84x + 539 = (x - 77 ) (x - 7)
