Here we answer the question: "What two numbers multiply to 677 and add up to -678?"

The answer to your question is:

-677 and -1

Below we illustrate and prove that -677 and -1 multiply to 677 and add up to -678:

-677 × -1 = 677
-677 + -1 = -678

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

x² - 678x + 677 = 0

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

(x - 677 ) (x - 1)

To summarize, since -677 and -1 multiply to 677 and add up -678, you know that the following is true:

x² - 678x + 677 = (x - 677 ) (x - 1)
