What two numbers multiply to -494 and add up to 245?

Here we answer the question: "What two numbers multiply to -494 and add up to 245?"

The answer to your question is:

-2 and 247

Below we illustrate and prove that -2 and 247 multiply to -494 and add up to 245:

-2 × 247 = -494
-2 + 247 = 245

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

x² + 245x - 494 = 0

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

(x - 2 ) (x + 247)

To summarize, since -2 and 247 multiply to -494 and add up 245, you know that the following is true:

x² + 245x - 494 = (x - 2 ) (x + 247)
