What two numbers multiply to -873 and add up to 872?

Here we answer the question: "What two numbers multiply to -873 and add up to 872?"

The answer to your question is:

-1 and 873

Below we illustrate and prove that -1 and 873 multiply to -873 and add up to 872:

-1 × 873 = -873
-1 + 873 = 872

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

x² + 872x - 873 = 0

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

(x - 1 ) (x + 873)

To summarize, since -1 and 873 multiply to -873 and add up 872, you know that the following is true:

x² + 872x - 873 = (x - 1 ) (x + 873)
