What two numbers multiply to 480 and add up to -47?

Here we answer the question: "What two numbers multiply to 480 and add up to -47?"

The answer to your question is:

-32 and -15

Below we illustrate and prove that -32 and -15 multiply to 480 and add up to -47:

-32 × -15 = 480
-32 + -15 = -47

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

x² - 47x + 480 = 0

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

(x - 32 ) (x - 15)

To summarize, since -32 and -15 multiply to 480 and add up -47, you know that the following is true:

x² - 47x + 480 = (x - 32 ) (x - 15)
