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

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

The answer to your question is:

-239 and -1

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

-239 × -1 = 239
-239 + -1 = -240

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

x² - 240x + 239 = 0

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

(x - 239 ) (x - 1)

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

x² - 240x + 239 = (x - 239 ) (x - 1)
