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

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

The answer to your question is:

-1 and 481

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

-1 × 481 = -481
-1 + 481 = 480

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

x² + 480x - 481 = 0

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

(x - 1 ) (x + 481)

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

x² + 480x - 481 = (x - 1 ) (x + 481)
