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:

-4 and 120

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

-4 × 120 = -480
-4 + 120 = 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 - 4 ) (x + 120)

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

x² + 116x - 480 = (x - 4 ) (x + 120)
