What two numbers multiply to -830 and add up to -413?

Here we answer the question: "What two numbers multiply to -830 and add up to -413?"

The answer to your question is:

-415 and 2

Below we illustrate and prove that -415 and 2 multiply to -830 and add up to -413:

-415 × 2 = -830
-415 + 2 = -413

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

x² - 413x - 830 = 0

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

(x - 415 ) (x + 2)

To summarize, since -415 and 2 multiply to -830 and add up -413, you know that the following is true:

x² - 413x - 830 = (x - 415 ) (x + 2)
