What two numbers multiply to -384 and add up to 8?

Here we answer the question: "What two numbers multiply to -384 and add up to 8?"

The answer to your question is:

-16 and 24

Below we illustrate and prove that -16 and 24 multiply to -384 and add up to 8:

-16 × 24 = -384
-16 + 24 = 8

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

x² + 8x - 384 = 0

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

(x - 16 ) (x + 24)

To summarize, since -16 and 24 multiply to -384 and add up 8, you know that the following is true:

x² + 8x - 384 = (x - 16 ) (x + 24)
