What two numbers multiply to 480 and add up to 52?

Here we answer the question: "What two numbers multiply to 480 and add up to 52?"

The answer to your question is:

12 and 40

Below we illustrate and prove that 12 and 40 multiply to 480 and add up to 52:

12 × 40 = 480
12 + 40 = 52

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

x² + 52x + 480 = 0

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

(x + 12 ) (x + 40)

To summarize, since 12 and 40 multiply to 480 and add up 52, you know that the following is true:

x² + 52x + 480 = (x + 12 ) (x + 40)
