What two numbers multiply to -226 and add up to 225?

Here we answer the question: "What two numbers multiply to -226 and add up to 225?"

The answer to your question is:

-1 and 226

Below we illustrate and prove that -1 and 226 multiply to -226 and add up to 225:

-1 × 226 = -226
-1 + 226 = 225

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

x² + 225x - 226 = 0

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

(x - 1 ) (x + 226)

To summarize, since -1 and 226 multiply to -226 and add up 225, you know that the following is true:

x² + 225x - 226 = (x - 1 ) (x + 226)
