Here we answer the question: "What two numbers multiply to 516 and add up to -517?"

The answer to your question is:

-516 and -1

Below we illustrate and prove that -516 and -1 multiply to 516 and add up to -517:

-516 × -1 = 516
-516 + -1 = -517

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

x² - 517x + 516 = 0

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

(x - 516 ) (x - 1)

To summarize, since -516 and -1 multiply to 516 and add up -517, you know that the following is true:

x² - 517x + 516 = (x - 516 ) (x - 1)
