What two numbers multiply to -480 and add up to -116?

Here we answer the question: "What two numbers multiply to -480 and add up to -116?"

The answer to your question is:

-120 and 4

Below we illustrate and prove that -120 and 4 multiply to -480 and add up to -116:

-120 × 4 = -480
-120 + 4 = -116

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

x² - 116x - 480 = 0

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

(x - 120 ) (x + 4)

To summarize, since -120 and 4 multiply to -480 and add up -116, you know that the following is true:

x² - 116x - 480 = (x - 120 ) (x + 4)
