What two numbers multiply to -814 and add up to 813?

Here we answer the question: "What two numbers multiply to -814 and add up to 813?"

The answer to your question is:

-1 and 814

Below we illustrate and prove that -1 and 814 multiply to -814 and add up to 813:

-1 × 814 = -814
-1 + 814 = 813

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

x² + 813x - 814 = 0

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

(x - 1 ) (x + 814)

To summarize, since -1 and 814 multiply to -814 and add up 813, you know that the following is true:

x² + 813x - 814 = (x - 1 ) (x + 814)
