What two numbers multiply to -866 and add up to 865?

Here we answer the question: "What two numbers multiply to -866 and add up to 865?"

The answer to your question is:

-1 and 866

Below we illustrate and prove that -1 and 866 multiply to -866 and add up to 865:

-1 × 866 = -866
-1 + 866 = 865

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

x² + 865x - 866 = 0

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

(x - 1 ) (x + 866)

To summarize, since -1 and 866 multiply to -866 and add up 865, you know that the following is true:

x² + 865x - 866 = (x - 1 ) (x + 866)
