Here we answer the question: "What two numbers multiply to 455 and add up to -456?"

The answer to your question is:

-455 and -1

Below we illustrate and prove that -455 and -1 multiply to 455 and add up to -456:

-455 × -1 = 455
-455 + -1 = -456

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

x² - 456x + 455 = 0

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

(x - 455 ) (x - 1)

To summarize, since -455 and -1 multiply to 455 and add up -456, you know that the following is true:

x² - 456x + 455 = (x - 455 ) (x - 1)
