What two numbers multiply to 663 and add up to -224?

Here we answer the question: "What two numbers multiply to 663 and add up to -224?"

The answer to your question is:

-221 and -3

Below we illustrate and prove that -221 and -3 multiply to 663 and add up to -224:

-221 × -3 = 663
-221 + -3 = -224

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

x² - 224x + 663 = 0

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

(x - 221 ) (x - 3)

To summarize, since -221 and -3 multiply to 663 and add up -224, you know that the following is true:

x² - 224x + 663 = (x - 221 ) (x - 3)
