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:

-4 and 140

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

-4 × 140 = -560
-4 + 140 = 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 - 4 ) (x + 140)

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

x² + 136x - 560 = (x - 4 ) (x + 140)
