The answer to your question is:

-385 and 1

Below we illustrate and prove that -385 and 1 multiply to -385 and add up to -384:

-385 × 1 = -385
-385 + 1 = -384

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

x² - 384x - 385 = 0

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

(x - 385 ) (x + 1)

To summarize, since -385 and 1 multiply to -385 and add up -384, you know that the following is true:

x² - 384x - 385 = (x - 385 ) (x + 1)
