Here we answer the question: "What two numbers multiply to 777 and add up to -778?"

The answer to your question is:

-777 and -1

Below we illustrate and prove that -777 and -1 multiply to 777 and add up to -778:

-777 × -1 = 777
-777 + -1 = -778

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

x² - 778x + 777 = 0

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

(x - 777 ) (x - 1)

To summarize, since -777 and -1 multiply to 777 and add up -778, you know that the following is true:

x² - 778x + 777 = (x - 777 ) (x - 1)
