What two numbers multiply to -864 and add up to 863?

Here we answer the question: "What two numbers multiply to -864 and add up to 863?"

The answer to your question is:

-1 and 864

Below we illustrate and prove that -1 and 864 multiply to -864 and add up to 863:

-1 × 864 = -864
-1 + 864 = 863

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

x² + 863x - 864 = 0

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

(x - 1 ) (x + 864)

To summarize, since -1 and 864 multiply to -864 and add up 863, you know that the following is true:

x² + 863x - 864 = (x - 1 ) (x + 864)
