Here we answer the question: "What two numbers multiply to -231 and add up to -230?"

The answer to your question is:

-231 and 1

Below we illustrate and prove that -231 and 1 multiply to -231 and add up to -230:

-231 × 1 = -231
-231 + 1 = -230

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

x² - 230x - 231 = 0

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

(x - 231 ) (x + 1)

To summarize, since -231 and 1 multiply to -231 and add up -230, you know that the following is true:

x² - 230x - 231 = (x - 231 ) (x + 1)
