What two numbers multiply to -824 and add up to 823?

Here we answer the question: "What two numbers multiply to -824 and add up to 823?"

The answer to your question is:

-1 and 824

Below we illustrate and prove that -1 and 824 multiply to -824 and add up to 823:

-1 × 824 = -824
-1 + 824 = 823

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

x² + 823x - 824 = 0

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

(x - 1 ) (x + 824)

To summarize, since -1 and 824 multiply to -824 and add up 823, you know that the following is true:

x² + 823x - 824 = (x - 1 ) (x + 824)
