What two numbers multiply to 808 and add up to -809?

Here we answer the question: "What two numbers multiply to 808 and add up to -809?"

The answer to your question is:

-808 and -1

Below we illustrate and prove that -808 and -1 multiply to 808 and add up to -809:

-808 × -1 = 808
-808 + -1 = -809

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

x² - 809x + 808 = 0

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

(x - 808 ) (x - 1)

To summarize, since -808 and -1 multiply to 808 and add up -809, you know that the following is true:

x² - 809x + 808 = (x - 808 ) (x - 1)
