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:

-2 and 415

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

-2 × 415 = -830
-2 + 415 = 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 - 2 ) (x + 415)

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

x² + 413x - 830 = (x - 2 ) (x + 415)
