What two numbers multiply to -580 and add up to 579?

Here we answer the question: "What two numbers multiply to -580 and add up to 579?"

The answer to your question is:

-1 and 580

Below we illustrate and prove that -1 and 580 multiply to -580 and add up to 579:

-1 × 580 = -580
-1 + 580 = 579

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

x² + 579x - 580 = 0

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

(x - 1 ) (x + 580)

To summarize, since -1 and 580 multiply to -580 and add up 579, you know that the following is true:

x² + 579x - 580 = (x - 1 ) (x + 580)
