What two numbers multiply to -224 and add up to 223?

Here we answer the question: "What two numbers multiply to -224 and add up to 223?"

The answer to your question is:

-1 and 224

Below we illustrate and prove that -1 and 224 multiply to -224 and add up to 223:

-1 × 224 = -224
-1 + 224 = 223

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

x² + 223x - 224 = 0

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

(x - 1 ) (x + 224)

To summarize, since -1 and 224 multiply to -224 and add up 223, you know that the following is true:

x² + 223x - 224 = (x - 1 ) (x + 224)
