What two numbers multiply to -687 and add up to 226?

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

The answer to your question is:

-3 and 229

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

-3 × 229 = -687
-3 + 229 = 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 - 3 ) (x + 229)

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

x² + 226x - 687 = (x - 3 ) (x + 229)
