What two numbers multiply to 877 and add up to -878?

Here we answer the question: "What two numbers multiply to 877 and add up to -878?"

The answer to your question is:

-877 and -1

Below we illustrate and prove that -877 and -1 multiply to 877 and add up to -878:

-877 × -1 = 877
-877 + -1 = -878

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

x² - 878x + 877 = 0

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

(x - 877 ) (x - 1)

To summarize, since -877 and -1 multiply to 877 and add up -878, you know that the following is true:

x² - 878x + 877 = (x - 877 ) (x - 1)
