What two numbers multiply to 480 and add up to -124?

Here we answer the question: "What two numbers multiply to 480 and add up to -124?"

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 -124:

-120 × -4 = 480
-120 + -4 = -124

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

x² - 124x + 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 -124, you know that the following is true:

x² - 124x + 480 = (x - 120 ) (x - 4)
