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

The answer to your question is:

-224 and 1

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

-224 × 1 = -224
-224 + 1 = -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 - 224 ) (x + 1)

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

x² - 223x - 224 = (x - 224 ) (x + 1)
