Here we answer the question: "What two numbers multiply to 478 and add up to -479?"

The answer to your question is:

-478 and -1

Below we illustrate and prove that -478 and -1 multiply to 478 and add up to -479:

-478 × -1 = 478
-478 + -1 = -479

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

x² - 479x + 478 = 0

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

(x - 478 ) (x - 1)

To summarize, since -478 and -1 multiply to 478 and add up -479, you know that the following is true:

x² - 479x + 478 = (x - 478 ) (x - 1)
