What two numbers multiply to -581 and add up to 580?

Here we answer the question: "What two numbers multiply to -581 and add up to 580?"

The answer to your question is:

-1 and 581

Below we illustrate and prove that -1 and 581 multiply to -581 and add up to 580:

-1 × 581 = -581
-1 + 581 = 580

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

x² + 580x - 581 = 0

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

(x - 1 ) (x + 581)

To summarize, since -1 and 581 multiply to -581 and add up 580, you know that the following is true:

x² + 580x - 581 = (x - 1 ) (x + 581)
