What two numbers multiply to -448 and add up to 222?

Here we answer the question: "What two numbers multiply to -448 and add up to 222?"

The answer to your question is:

-2 and 224

Below we illustrate and prove that -2 and 224 multiply to -448 and add up to 222:

-2 × 224 = -448
-2 + 224 = 222

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

x² + 222x - 448 = 0

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

(x - 2 ) (x + 224)

To summarize, since -2 and 224 multiply to -448 and add up 222, you know that the following is true:

x² + 222x - 448 = (x - 2 ) (x + 224)
