What two numbers multiply to 669 and add up to -226?

Here we answer the question: "What two numbers multiply to 669 and add up to -226?"

The answer to your question is:

-223 and -3

Below we illustrate and prove that -223 and -3 multiply to 669 and add up to -226:

-223 × -3 = 669
-223 + -3 = -226

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

x² - 226x + 669 = 0

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

(x - 223 ) (x - 3)

To summarize, since -223 and -3 multiply to 669 and add up -226, you know that the following is true:

x² - 226x + 669 = (x - 223 ) (x - 3)
