What two numbers multiply to -980 and add up to -88?

Here we answer the question: "What two numbers multiply to -980 and add up to -88?"

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 -88:

-98 × 10 = -980
-98 + 10 = -88

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

x² - 88x - 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 -88, you know that the following is true:

x² - 88x - 980 = (x - 98 ) (x + 10)
