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:

-9 and 12

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

-9 × 12 = -108
-9 + 12 = 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 - 9 ) (x + 12)

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

x² + 3x - 108 = (x - 9 ) (x + 12)
