What two numbers multiply to -108 and add up to -3?

Here we answer the question: "What two numbers multiply to -108 and add up to -3?"

The answer to your question is:

-12 and 9

Below we illustrate and prove that -12 and 9 multiply to -108 and add up to -3:

-12 × 9 = -108
-12 + 9 = -3

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

x² - 3x - 108 = 0

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

(x - 12 ) (x + 9)

To summarize, since -12 and 9 multiply to -108 and add up -3, you know that the following is true:

x² - 3x - 108 = (x - 12 ) (x + 9)
