What two numbers multiply to -810 and add up to -809?

Here we answer the question: "What two numbers multiply to -810 and add up to -809?"

The answer to your question is:

-810 and 1

Below we illustrate and prove that -810 and 1 multiply to -810 and add up to -809:

-810 × 1 = -810
-810 + 1 = -809

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

x² - 809x - 810 = 0

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

(x - 810 ) (x + 1)

To summarize, since -810 and 1 multiply to -810 and add up -809, you know that the following is true:

x² - 809x - 810 = (x - 810 ) (x + 1)
