What two numbers multiply to -864 and add up to -12?

Here we answer the question: "What two numbers multiply to -864 and add up to -12?"

The answer to your question is:

-36 and 24

Below we illustrate and prove that -36 and 24 multiply to -864 and add up to -12:

-36 × 24 = -864
-36 + 24 = -12

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

x² - 12x - 864 = 0

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

(x - 36 ) (x + 24)

To summarize, since -36 and 24 multiply to -864 and add up -12, you know that the following is true:

x² - 12x - 864 = (x - 36 ) (x + 24)
