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:

15 and 32

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

15 × 32 = 480
15 + 32 = 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 + 15 ) (x + 32)

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

x² + 47x + 480 = (x + 15 ) (x + 32)
