What two numbers multiply to 980 and add up to -108?

Here we answer the question: "What two numbers multiply to 980 and add up to -108?"

The answer to your question is:

-98 and -10

Below we illustrate and prove that -98 and -10 multiply to 980 and add up to -108:

-98 × -10 = 980
-98 + -10 = -108

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

x² - 108x + 980 = 0

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

(x - 98 ) (x - 10)

To summarize, since -98 and -10 multiply to 980 and add up -108, you know that the following is true:

x² - 108x + 980 = (x - 98 ) (x - 10)
