Here we answer the question: "What two numbers multiply to 977 and add up to -978?"

The answer to your question is:

-977 and -1

Below we illustrate and prove that -977 and -1 multiply to 977 and add up to -978:

-977 × -1 = 977
-977 + -1 = -978

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

x² - 978x + 977 = 0

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

(x - 977 ) (x - 1)

To summarize, since -977 and -1 multiply to 977 and add up -978, you know that the following is true:

x² - 978x + 977 = (x - 977 ) (x - 1)
