Here we answer the question: "What two numbers multiply to -498 and add up to 497?"

The answer to your question is:

-1 and 498

Below we illustrate and prove that -1 and 498 multiply to -498 and add up to 497:

-1 × 498 = -498
-1 + 498 = 497

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

x² + 497x - 498 = 0

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

(x - 1 ) (x + 498)

To summarize, since -1 and 498 multiply to -498 and add up 497, you know that the following is true:

x² + 497x - 498 = (x - 1 ) (x + 498)
