What two numbers multiply to -680 and add up to -338?

Here we answer the question: "What two numbers multiply to -680 and add up to -338?"

The answer to your question is:

-340 and 2

Below we illustrate and prove that -340 and 2 multiply to -680 and add up to -338:

-340 × 2 = -680
-340 + 2 = -338

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

x² - 338x - 680 = 0

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

(x - 340 ) (x + 2)

To summarize, since -340 and 2 multiply to -680 and add up -338, you know that the following is true:

x² - 338x - 680 = (x - 340 ) (x + 2)
