What two numbers multiply to -223 and add up to -222?

Here we answer the question: "What two numbers multiply to -223 and add up to -222?"

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 -222:

-223 × 1 = -223
-223 + 1 = -222

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

x² - 222x - 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 -222, you know that the following is true:

x² - 222x - 223 = (x - 223 ) (x + 1)
