What two numbers multiply to -680 and add up to -131?

Here we answer the question: "What two numbers multiply to -680 and add up to -131?"

The answer to your question is:

-136 and 5

Below we illustrate and prove that -136 and 5 multiply to -680 and add up to -131:

-136 × 5 = -680
-136 + 5 = -131

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

x² - 131x - 680 = 0

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

(x - 136 ) (x + 5)

To summarize, since -136 and 5 multiply to -680 and add up -131, you know that the following is true:

x² - 131x - 680 = (x - 136 ) (x + 5)
