What two numbers multiply to -680 and add up to -58?

Here we answer the question: "What two numbers multiply to -680 and add up to -58?"

The answer to your question is:

-68 and 10

Below we illustrate and prove that -68 and 10 multiply to -680 and add up to -58:

-68 × 10 = -680
-68 + 10 = -58

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

x² - 58x - 680 = 0

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

(x - 68 ) (x + 10)

To summarize, since -68 and 10 multiply to -680 and add up -58, you know that the following is true:

x² - 58x - 680 = (x - 68 ) (x + 10)
