What two numbers multiply to -384 and add up to 383?

Here we answer the question: "What two numbers multiply to -384 and add up to 383?"

The answer to your question is:

-1 and 384

Below we illustrate and prove that -1 and 384 multiply to -384 and add up to 383:

-1 × 384 = -384
-1 + 384 = 383

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

x² + 383x - 384 = 0

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

(x - 1 ) (x + 384)

To summarize, since -1 and 384 multiply to -384 and add up 383, you know that the following is true:

x² + 383x - 384 = (x - 1 ) (x + 384)
