What two numbers multiply to -230 and add up to 229?

Here we answer the question: "What two numbers multiply to -230 and add up to 229?"

The answer to your question is:

-1 and 230

Below we illustrate and prove that -1 and 230 multiply to -230 and add up to 229:

-1 × 230 = -230
-1 + 230 = 229

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

x² + 229x - 230 = 0

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

(x - 1 ) (x + 230)

To summarize, since -1 and 230 multiply to -230 and add up 229, you know that the following is true:

x² + 229x - 230 = (x - 1 ) (x + 230)
