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:

3 and 221

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

3 × 221 = 663
3 + 221 = 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 + 3 ) (x + 221)

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

x² + 224x + 663 = (x + 3 ) (x + 221)
