Here we answer the question: "What two numbers multiply to -255 and add up to -254?"

The answer to your question is:

-255 and 1

Below we illustrate and prove that -255 and 1 multiply to -255 and add up to -254:

-255 × 1 = -255
-255 + 1 = -254

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

x² - 254x - 255 = 0
