What two numbers multiply to -982 and add up to 489?

Here we answer the question: "What two numbers multiply to -982 and add up to 489?"

The answer to your question is:

-2 and 491

Below we illustrate and prove that -2 and 491 multiply to -982 and add up to 489:

-2 × 491 = -982
-2 + 491 = 489

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

x² + 489x - 982 = 0

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

(x - 2 ) (x + 491)

To summarize, since -2 and 491 multiply to -982 and add up 489, you know that the following is true:

x² + 489x - 982 = (x - 2 ) (x + 491)
