Here we answer the question: "What two numbers multiply to -822 and add up to -821?"

The answer to your question is:

-822 and 1

Below we illustrate and prove that -822 and 1 multiply to -822 and add up to -821:

-822 × 1 = -822
-822 + 1 = -821

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

x² - 821x - 822 = 0
