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:

-23 and 10

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

-23 × 10 = -230
-23 + 10 = -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 - 23 ) (x + 10)

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

x² - 13x - 230 = (x - 23 ) (x + 10)
