What two numbers multiply to 384 and add up to -131?

Here we answer the question: "What two numbers multiply to 384 and add up to -131?"

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 -131:

-128 × -3 = 384
-128 + -3 = -131

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

x² - 131x + 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 -131, you know that the following is true:

x² - 131x + 384 = (x - 128 ) (x - 3)
