What two numbers multiply to -998 and add up to 497?

Here we answer the question: "What two numbers multiply to -998 and add up to 497?"

The answer to your question is:

-2 and 499

Below we illustrate and prove that -2 and 499 multiply to -998 and add up to 497:

-2 × 499 = -998
-2 + 499 = 497

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

x² + 497x - 998 = 0

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

(x - 2 ) (x + 499)

To summarize, since -2 and 499 multiply to -998 and add up 497, you know that the following is true:

x² + 497x - 998 = (x - 2 ) (x + 499)
