What two numbers multiply to -240 and add up to -239?

Here we answer the question: "What two numbers multiply to -240 and add up to -239?"

The answer to your question is:

-240 and 1

Below we illustrate and prove that -240 and 1 multiply to -240 and add up to -239:

-240 × 1 = -240
-240 + 1 = -239

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

x² - 239x - 240 = 0

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

(x - 240 ) (x + 1)

To summarize, since -240 and 1 multiply to -240 and add up -239, you know that the following is true:

x² - 239x - 240 = (x - 240 ) (x + 1)
