Here we answer the question: "What two numbers multiply to -865 and add up to -864?"

The answer to your question is:

-865 and 1

Below we illustrate and prove that -865 and 1 multiply to -865 and add up to -864:

-865 × 1 = -865
-865 + 1 = -864

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

x² - 864x - 865 = 0

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

(x - 865 ) (x + 1)

To summarize, since -865 and 1 multiply to -865 and add up -864, you know that the following is true:

x² - 864x - 865 = (x - 865 ) (x + 1)
