Here we answer the question: "What two numbers multiply to 517 and add up to -518?"

The answer to your question is:

-517 and -1

Below we illustrate and prove that -517 and -1 multiply to 517 and add up to -518:

-517 × -1 = 517
-517 + -1 = -518

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

x² - 518x + 517 = 0

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

(x - 517 ) (x - 1)

To summarize, since -517 and -1 multiply to 517 and add up -518, you know that the following is true:

x² - 518x + 517 = (x - 517 ) (x - 1)
