What two numbers multiply to 480 and add up to 481?

Here we answer the question: "What two numbers multiply to 480 and add up to 481?"

The answer to your question is:

1 and 480

Below we illustrate and prove that 1 and 480 multiply to 480 and add up to 481:

1 × 480 = 480
1 + 480 = 481

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

x² + 481x + 480 = 0

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

(x + 1 ) (x + 480)

To summarize, since 1 and 480 multiply to 480 and add up 481, you know that the following is true:

x² + 481x + 480 = (x + 1 ) (x + 480)
