What two numbers multiply to -519 and add up to 518?

Here we answer the question: "What two numbers multiply to -519 and add up to 518?"

The answer to your question is:

-1 and 519

Below we illustrate and prove that -1 and 519 multiply to -519 and add up to 518:

-1 × 519 = -519
-1 + 519 = 518

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

x² + 518x - 519 = 0

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

(x - 1 ) (x + 519)

To summarize, since -1 and 519 multiply to -519 and add up 518, you know that the following is true:

x² + 518x - 519 = (x - 1 ) (x + 519)
