What two numbers multiply to -580 and add up to 9?

Here we answer the question: "What two numbers multiply to -580 and add up to 9?"

The answer to your question is:

-20 and 29

Below we illustrate and prove that -20 and 29 multiply to -580 and add up to 9:

-20 × 29 = -580
-20 + 29 = 9

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

x² + 9x - 580 = 0

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

(x - 20 ) (x + 29)

To summarize, since -20 and 29 multiply to -580 and add up 9, you know that the following is true:

x² + 9x - 580 = (x - 20 ) (x + 29)
