What two numbers multiply to 515 and add up to -516?

Here we answer the question: "What two numbers multiply to 515 and add up to -516?"

The answer to your question is:

-515 and -1

Below we illustrate and prove that -515 and -1 multiply to 515 and add up to -516:

-515 × -1 = 515
-515 + -1 = -516

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

x² - 516x + 515 = 0

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

(x - 515 ) (x - 1)

To summarize, since -515 and -1 multiply to 515 and add up -516, you know that the following is true:

x² - 516x + 515 = (x - 515 ) (x - 1)
