What two numbers multiply to -868 and add up to 867?

Here we answer the question: "What two numbers multiply to -868 and add up to 867?"

The answer to your question is:

-1 and 868

Below we illustrate and prove that -1 and 868 multiply to -868 and add up to 867:

-1 × 868 = -868
-1 + 868 = 867

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

x² + 867x - 868 = 0

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

(x - 1 ) (x + 868)

To summarize, since -1 and 868 multiply to -868 and add up 867, you know that the following is true:

x² + 867x - 868 = (x - 1 ) (x + 868)
