Here we answer the question: "What two numbers multiply to -687 and add up to -226?"

The answer to your question is:

-229 and 3

Below we illustrate and prove that -229 and 3 multiply to -687 and add up to -226:

-229 × 3 = -687
-229 + 3 = -226

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

x² - 226x - 687 = 0

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

(x - 229 ) (x + 3)

To summarize, since -229 and 3 multiply to -687 and add up -226, you know that the following is true:

x² - 226x - 687 = (x - 229 ) (x + 3)
