What two numbers multiply to -231 and add up to 230?

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

The answer to your question is:

-1 and 231

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

-1 × 231 = -231
-1 + 231 = 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 - 1 ) (x + 231)

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

x² + 230x - 231 = (x - 1 ) (x + 231)
