What two numbers multiply to 680 and add up to -342?

Here we answer the question: "What two numbers multiply to 680 and add up to -342?"

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 -342:

-340 × -2 = 680
-340 + -2 = -342

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

x² - 342x + 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 -342, you know that the following is true:

x² - 342x + 680 = (x - 340 ) (x - 2)
