What two numbers multiply to -561 and add up to 560?

Here we answer the question: "What two numbers multiply to -561 and add up to 560?"

The answer to your question is:

-1 and 561

Below we illustrate and prove that -1 and 561 multiply to -561 and add up to 560:

-1 × 561 = -561
-1 + 561 = 560

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

x² + 560x - 561 = 0

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

(x - 1 ) (x + 561)

To summarize, since -1 and 561 multiply to -561 and add up 560, you know that the following is true:

x² + 560x - 561 = (x - 1 ) (x + 561)
