What two numbers multiply to -216 and add up to -6?

Here we answer the question: "What two numbers multiply to -216 and add up to -6?"

The answer to your question is:

-18 and 12

Below we illustrate and prove that -18 and 12 multiply to -216 and add up to -6:

-18 × 12 = -216
-18 + 12 = -6

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

x² - 6x - 216 = 0

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

(x - 18 ) (x + 12)

To summarize, since -18 and 12 multiply to -216 and add up -6, you know that the following is true:

x² - 6x - 216 = (x - 18 ) (x + 12)
