Here we answer the question: "What two numbers multiply to -498 and add up to 247?"

The answer to your question is:

-2 and 249

Below we illustrate and prove that -2 and 249 multiply to -498 and add up to 247:

-2 × 249 = -498
-2 + 249 = 247

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

x² + 247x - 498 = 0

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

(x - 2 ) (x + 249)

To summarize, since -2 and 249 multiply to -498 and add up 247, you know that the following is true:

x² + 247x - 498 = (x - 2 ) (x + 249)
