What two numbers multiply to -240 and add up to -22?

Here we answer the question: "What two numbers multiply to -240 and add up to -22?"

The answer to your question is:

-30 and 8

Below we illustrate and prove that -30 and 8 multiply to -240 and add up to -22:

-30 × 8 = -240
-30 + 8 = -22

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

x² - 22x - 240 = 0

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

(x - 30 ) (x + 8)

To summarize, since -30 and 8 multiply to -240 and add up -22, you know that the following is true:

x² - 22x - 240 = (x - 30 ) (x + 8)
