What two numbers multiply to -720 and add up to -22?

Here we answer the question: "What two numbers multiply to -720 and add up to -22?"

The answer to your question is:

-40 and 18

Below we illustrate and prove that -40 and 18 multiply to -720 and add up to -22:

-40 × 18 = -720
-40 + 18 = -22

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

x² - 22x - 720 = 0

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

(x - 40 ) (x + 18)

To summarize, since -40 and 18 multiply to -720 and add up -22, you know that the following is true:

x² - 22x - 720 = (x - 40 ) (x + 18)
