What two numbers multiply to -684 and add up to 340?

Here we answer the question: "What two numbers multiply to -684 and add up to 340?"

The answer to your question is:

-2 and 342

Below we illustrate and prove that -2 and 342 multiply to -684 and add up to 340:

-2 × 342 = -684
-2 + 342 = 340

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

x² + 340x - 684 = 0

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

(x - 2 ) (x + 342)

To summarize, since -2 and 342 multiply to -684 and add up 340, you know that the following is true:

x² + 340x - 684 = (x - 2 ) (x + 342)
