What two numbers multiply to -843 and add up to 842?

Here we answer the question: "What two numbers multiply to -843 and add up to 842?"

The answer to your question is:

-1 and 843

Below we illustrate and prove that -1 and 843 multiply to -843 and add up to 842:

-1 × 843 = -843
-1 + 843 = 842

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

x² + 842x - 843 = 0

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

(x - 1 ) (x + 843)

To summarize, since -1 and 843 multiply to -843 and add up 842, you know that the following is true:

x² + 842x - 843 = (x - 1 ) (x + 843)
