What two numbers multiply to -485 and add up to 484?

Here we answer the question: "What two numbers multiply to -485 and add up to 484?"

The answer to your question is:

-1 and 485

Below we illustrate and prove that -1 and 485 multiply to -485 and add up to 484:

-1 × 485 = -485
-1 + 485 = 484

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

x² + 484x - 485 = 0

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

(x - 1 ) (x + 485)

To summarize, since -1 and 485 multiply to -485 and add up 484, you know that the following is true:

x² + 484x - 485 = (x - 1 ) (x + 485)
