What two numbers multiply to 814 and add up to -815?

Here we answer the question: "What two numbers multiply to 814 and add up to -815?"

The answer to your question is:

-814 and -1

Below we illustrate and prove that -814 and -1 multiply to 814 and add up to -815:

-814 × -1 = 814
-814 + -1 = -815

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

x² - 815x + 814 = 0

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

(x - 814 ) (x - 1)

To summarize, since -814 and -1 multiply to 814 and add up -815, you know that the following is true:

x² - 815x + 814 = (x - 814 ) (x - 1)
