What two numbers multiply to -980 and add up to 488?

Here we answer the question: "What two numbers multiply to -980 and add up to 488?"

The answer to your question is:

-2 and 490

Below we illustrate and prove that -2 and 490 multiply to -980 and add up to 488:

-2 × 490 = -980
-2 + 490 = 488

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

x² + 488x - 980 = 0

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

(x - 2 ) (x + 490)

To summarize, since -2 and 490 multiply to -980 and add up 488, you know that the following is true:

x² + 488x - 980 = (x - 2 ) (x + 490)
