What two numbers multiply to 278 and add up to -279?

Here we answer the question: "What two numbers multiply to 278 and add up to -279?"

The answer to your question is:

-278 and -1

Below we illustrate and prove that -278 and -1 multiply to 278 and add up to -279:

-278 × -1 = 278
-278 + -1 = -279

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

x² - 279x + 278 = 0

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

(x - 278 ) (x - 1)

To summarize, since -278 and -1 multiply to 278 and add up -279, you know that the following is true:

x² - 279x + 278 = (x - 278 ) (x - 1)
