What two numbers multiply to 980 and add up to -492?

Here we answer the question: "What two numbers multiply to 980 and add up to -492?"

The answer to your question is:

-490 and -2

Below we illustrate and prove that -490 and -2 multiply to 980 and add up to -492:

-490 × -2 = 980
-490 + -2 = -492

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

x² - 492x + 980 = 0

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

(x - 490 ) (x - 2)

To summarize, since -490 and -2 multiply to 980 and add up -492, you know that the following is true:

x² - 492x + 980 = (x - 490 ) (x - 2)
