What two numbers multiply to -225 and add up to 224?

Here we answer the question: "What two numbers multiply to -225 and add up to 224?"

The answer to your question is:

-1 and 225

Below we illustrate and prove that -1 and 225 multiply to -225 and add up to 224:

-1 × 225 = -225
-1 + 225 = 224

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

x² + 224x - 225 = 0

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

(x - 1 ) (x + 225)

To summarize, since -1 and 225 multiply to -225 and add up 224, you know that the following is true:

x² + 224x - 225 = (x - 1 ) (x + 225)
