What two numbers multiply to -518 and add up to 517?

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

The answer to your question is:

-1 and 518

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

-1 × 518 = -518
-1 + 518 = 517

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

x² + 517x - 518 = 0

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

(x - 1 ) (x + 518)

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

x² + 517x - 518 = (x - 1 ) (x + 518)
