What two numbers multiply to -861 and add up to 860?

Here we answer the question: "What two numbers multiply to -861 and add up to 860?"

The answer to your question is:

-1 and 861

Below we illustrate and prove that -1 and 861 multiply to -861 and add up to 860:

-1 × 861 = -861
-1 + 861 = 860

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

x² + 860x - 861 = 0

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

(x - 1 ) (x + 861)

To summarize, since -1 and 861 multiply to -861 and add up 860, you know that the following is true:

x² + 860x - 861 = (x - 1 ) (x + 861)
