What two numbers multiply to -384 and add up to -125?

Here we answer the question: "What two numbers multiply to -384 and add up to -125?"

The answer to your question is:

-128 and 3

Below we illustrate and prove that -128 and 3 multiply to -384 and add up to -125:

-128 × 3 = -384
-128 + 3 = -125

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

x² - 125x - 384 = 0

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

(x - 128 ) (x + 3)

To summarize, since -128 and 3 multiply to -384 and add up -125, you know that the following is true:

x² - 125x - 384 = (x - 128 ) (x + 3)
