What two numbers multiply to -446 and add up to 221?

Here we answer the question: "What two numbers multiply to -446 and add up to 221?"

The answer to your question is:

-2 and 223

Below we illustrate and prove that -2 and 223 multiply to -446 and add up to 221:

-2 × 223 = -446
-2 + 223 = 221

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

x² + 221x - 446 = 0

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

(x - 2 ) (x + 223)

To summarize, since -2 and 223 multiply to -446 and add up 221, you know that the following is true:

x² + 221x - 446 = (x - 2 ) (x + 223)
