What two numbers multiply to -801 and add up to -800?

Here we answer the question: "What two numbers multiply to -801 and add up to -800?"

The answer to your question is:

-801 and 1

Below we illustrate and prove that -801 and 1 multiply to -801 and add up to -800:

-801 × 1 = -801
-801 + 1 = -800

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

x² - 800x - 801 = 0

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

(x - 801 ) (x + 1)

To summarize, since -801 and 1 multiply to -801 and add up -800, you know that the following is true:

x² - 800x - 801 = (x - 801 ) (x + 1)
