What two numbers multiply to -22 and add up to -9?

Here we answer the question: "What two numbers multiply to -22 and add up to -9?"

The answer to your question is:

-11 and 2

Below we illustrate and prove that -11 and 2 multiply to -22 and add up to -9:

-11 × 2 = -22
-11 + 2 = -9

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

x² - 9x - 22 = 0

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

(x - 11 ) (x + 2)

To summarize, since -11 and 2 multiply to -22 and add up -9, you know that the following is true:

x² - 9x - 22 = (x - 11 ) (x + 2)
