What two numbers multiply to -680 and add up to -23?

Here we answer the question: "What two numbers multiply to -680 and add up to -23?"

The answer to your question is:

-40 and 17

Below we illustrate and prove that -40 and 17 multiply to -680 and add up to -23:

-40 × 17 = -680
-40 + 17 = -23

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

x² - 23x - 680 = 0

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

(x - 40 ) (x + 17)

To summarize, since -40 and 17 multiply to -680 and add up -23, you know that the following is true:

x² - 23x - 680 = (x - 40 ) (x + 17)
