Here we answer the question: "What two numbers multiply to 817 and add up to -818?"

The answer to your question is:

-817 and -1

Below we illustrate and prove that -817 and -1 multiply to 817 and add up to -818:

-817 × -1 = 817
-817 + -1 = -818

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

x² - 818x + 817 = 0
