What two numbers multiply to -560 and add up to -136?

Here we answer the question: "What two numbers multiply to -560 and add up to -136?"

The answer to your question is:

-140 and 4

Below we illustrate and prove that -140 and 4 multiply to -560 and add up to -136:

-140 × 4 = -560
-140 + 4 = -136

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

x² - 136x - 560 = 0

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

(x - 140 ) (x + 4)

To summarize, since -140 and 4 multiply to -560 and add up -136, you know that the following is true:

x² - 136x - 560 = (x - 140 ) (x + 4)
