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:

-229 and 4

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

-229 × 4 = -916
-229 + 4 = -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 - 229 ) (x + 4)

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

x² - 225x - 916 = (x - 229 ) (x + 4)
