What two numbers multiply to 831 and add up to -280?

Here we answer the question: "What two numbers multiply to 831 and add up to -280?"

The answer to your question is:

-277 and -3

Below we illustrate and prove that -277 and -3 multiply to 831 and add up to -280:

-277 × -3 = 831
-277 + -3 = -280

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

x² - 280x + 831 = 0

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

(x - 277 ) (x - 3)

To summarize, since -277 and -3 multiply to 831 and add up -280, you know that the following is true:

x² - 280x + 831 = (x - 277 ) (x - 3)
