What two numbers multiply to -880 and add up to 438?

Here we answer the question: "What two numbers multiply to -880 and add up to 438?"

The answer to your question is:

-2 and 440

Below we illustrate and prove that -2 and 440 multiply to -880 and add up to 438:

-2 × 440 = -880
-2 + 440 = 438

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

x² + 438x - 880 = 0

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

(x - 2 ) (x + 440)

To summarize, since -2 and 440 multiply to -880 and add up 438, you know that the following is true:

x² + 438x - 880 = (x - 2 ) (x + 440)
