What two numbers multiply to -240 and add up to -56?

Here we answer the question: "What two numbers multiply to -240 and add up to -56?"

The answer to your question is:

-60 and 4

Below we illustrate and prove that -60 and 4 multiply to -240 and add up to -56:

-60 × 4 = -240
-60 + 4 = -56

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

x² - 56x - 240 = 0

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

(x - 60 ) (x + 4)

To summarize, since -60 and 4 multiply to -240 and add up -56, you know that the following is true:

x² - 56x - 240 = (x - 60 ) (x + 4)
