What two numbers multiply to -108 and add up to -12?

Here we answer the question: "What two numbers multiply to -108 and add up to -12?"

The answer to your question is:

-18 and 6

Below we illustrate and prove that -18 and 6 multiply to -108 and add up to -12:

-18 × 6 = -108
-18 + 6 = -12

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

x² - 12x - 108 = 0

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

(x - 18 ) (x + 6)

To summarize, since -18 and 6 multiply to -108 and add up -12, you know that the following is true:

x² - 12x - 108 = (x - 18 ) (x + 6)
