What two numbers multiply to 254 and add up to -255?

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

The answer to your question is:

-254 and -1

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

-254 × -1 = 254
-254 + -1 = -255

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

x² - 255x + 254 = 0

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

(x - 254 ) (x - 1)

To summarize, since -254 and -1 multiply to 254 and add up -255, you know that the following is true:

x² - 255x + 254 = (x - 254 ) (x - 1)
