What two numbers multiply to 556 and add up to -280?

Here we answer the question: "What two numbers multiply to 556 and add up to -280?"

The answer to your question is:

-278 and -2

Below we illustrate and prove that -278 and -2 multiply to 556 and add up to -280:

-278 × -2 = 556
-278 + -2 = -280

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

x² - 280x + 556 = 0

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

(x - 278 ) (x - 2)

To summarize, since -278 and -2 multiply to 556 and add up -280, you know that the following is true:

x² - 280x + 556 = (x - 278 ) (x - 2)
