What two numbers multiply to -108 and add up to -23?

Here we answer the question: "What two numbers multiply to -108 and add up to -23?"

The answer to your question is:

-27 and 4

Below we illustrate and prove that -27 and 4 multiply to -108 and add up to -23:

-27 × 4 = -108
-27 + 4 = -23

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

x² - 23x - 108 = 0

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

(x - 27 ) (x + 4)

To summarize, since -27 and 4 multiply to -108 and add up -23, you know that the following is true:

x² - 23x - 108 = (x - 27 ) (x + 4)
