What two numbers multiply to -560 and add up to 559?

Here we answer the question: "What two numbers multiply to -560 and add up to 559?"

The answer to your question is:

-1 and 560

Below we illustrate and prove that -1 and 560 multiply to -560 and add up to 559:

-1 × 560 = -560
-1 + 560 = 559

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

x² + 559x - 560 = 0

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

(x - 1 ) (x + 560)

To summarize, since -1 and 560 multiply to -560 and add up 559, you know that the following is true:

x² + 559x - 560 = (x - 1 ) (x + 560)
