What two numbers multiply to 980 and add up to -84?

Here we answer the question: "What two numbers multiply to 980 and add up to -84?"

The answer to your question is:

-70 and -14

Below we illustrate and prove that -70 and -14 multiply to 980 and add up to -84:

-70 × -14 = 980
-70 + -14 = -84

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

x² - 84x + 980 = 0

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

(x - 70 ) (x - 14)

To summarize, since -70 and -14 multiply to 980 and add up -84, you know that the following is true:

x² - 84x + 980 = (x - 70 ) (x - 14)
