What two numbers multiply to 277 and add up to -278?

Here we answer the question: "What two numbers multiply to 277 and add up to -278?"

The answer to your question is:

-277 and -1

Below we illustrate and prove that -277 and -1 multiply to 277 and add up to -278:

-277 × -1 = 277
-277 + -1 = -278

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

x² - 278x + 277 = 0

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

(x - 277 ) (x - 1)

To summarize, since -277 and -1 multiply to 277 and add up -278, you know that the following is true:

x² - 278x + 277 = (x - 277 ) (x - 1)
