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:

-1 and 223

Below we illustrate and prove that -1 and 223 multiply to -223 and add up to 222:

-1 × 223 = -223
-1 + 223 = 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 - 1 ) (x + 223)

To summarize, since -1 and 223 multiply to -223 and add up 222, you know that the following is true:

x² + 222x - 223 = (x - 1 ) (x + 223)
