What two numbers multiply to -823 and add up to 822?

Here we answer the question: "What two numbers multiply to -823 and add up to 822?"

The answer to your question is:

-1 and 823

Below we illustrate and prove that -1 and 823 multiply to -823 and add up to 822:

-1 × 823 = -823
-1 + 823 = 822

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

x² + 822x - 823 = 0

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

(x - 1 ) (x + 823)

To summarize, since -1 and 823 multiply to -823 and add up 822, you know that the following is true:

x² + 822x - 823 = (x - 1 ) (x + 823)
