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:

-24 and 36

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

-24 × 36 = -864
-24 + 36 = 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 - 24 ) (x + 36)

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

x² + 12x - 864 = (x - 24 ) (x + 36)
