What two numbers multiply to -678 and add up to 337?

Here we answer the question: "What two numbers multiply to -678 and add up to 337?"

The answer to your question is:

-2 and 339

Below we illustrate and prove that -2 and 339 multiply to -678 and add up to 337:

-2 × 339 = -678
-2 + 339 = 337

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

x² + 337x - 678 = 0

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

(x - 2 ) (x + 339)

To summarize, since -2 and 339 multiply to -678 and add up 337, you know that the following is true:

x² + 337x - 678 = (x - 2 ) (x + 339)
