What two numbers multiply to -880 and add up to 18?

Here we answer the question: "What two numbers multiply to -880 and add up to 18?"

The answer to your question is:

-22 and 40

Below we illustrate and prove that -22 and 40 multiply to -880 and add up to 18:

-22 × 40 = -880
-22 + 40 = 18

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

x² + 18x - 880 = 0

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

(x - 22 ) (x + 40)

To summarize, since -22 and 40 multiply to -880 and add up 18, you know that the following is true:

x² + 18x - 880 = (x - 22 ) (x + 40)
