What two numbers multiply to -239 and add up to 238?

Here we answer the question: "What two numbers multiply to -239 and add up to 238?"

The answer to your question is:

-1 and 239

Below we illustrate and prove that -1 and 239 multiply to -239 and add up to 238:

-1 × 239 = -239
-1 + 239 = 238

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

x² + 238x - 239 = 0

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

(x - 1 ) (x + 239)

To summarize, since -1 and 239 multiply to -239 and add up 238, you know that the following is true:

x² + 238x - 239 = (x - 1 ) (x + 239)
