What two numbers multiply to 223 and add up to -224?

Here we answer the question: "What two numbers multiply to 223 and add up to -224?"

The answer to your question is:

-223 and -1

Below we illustrate and prove that -223 and -1 multiply to 223 and add up to -224:

-223 × -1 = 223
-223 + -1 = -224

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

x² - 224x + 223 = 0

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

(x - 223 ) (x - 1)

To summarize, since -223 and -1 multiply to 223 and add up -224, you know that the following is true:

x² - 224x + 223 = (x - 223 ) (x - 1)
