What two numbers multiply to -230 and add up to 13?

Here we answer the question: "What two numbers multiply to -230 and add up to 13?"

The answer to your question is:

-10 and 23

Below we illustrate and prove that -10 and 23 multiply to -230 and add up to 13:

-10 × 23 = -230
-10 + 23 = 13

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

x² + 13x - 230 = 0

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

(x - 10 ) (x + 23)

To summarize, since -10 and 23 multiply to -230 and add up 13, you know that the following is true:

x² + 13x - 230 = (x - 10 ) (x + 23)
