What two numbers multiply to -279 and add up to -22?

Here we answer the question: "What two numbers multiply to -279 and add up to -22?"

The answer to your question is:

-31 and 9

Below we illustrate and prove that -31 and 9 multiply to -279 and add up to -22:

-31 × 9 = -279
-31 + 9 = -22

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

x² - 22x - 279 = 0

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

(x - 31 ) (x + 9)

To summarize, since -31 and 9 multiply to -279 and add up -22, you know that the following is true:

x² - 22x - 279 = (x - 31 ) (x + 9)
