What two numbers multiply to -916 and add up to 225?

Here we answer the question: "What two numbers multiply to -916 and add up to 225?"

The answer to your question is:

-4 and 229

Below we illustrate and prove that -4 and 229 multiply to -916 and add up to 225:

-4 × 229 = -916
-4 + 229 = 225

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

x² + 225x - 916 = 0

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

(x - 4 ) (x + 229)

To summarize, since -4 and 229 multiply to -916 and add up 225, you know that the following is true:

x² + 225x - 916 = (x - 4 ) (x + 229)
