What two numbers multiply to -980 and add up to -979?

Here we answer the question: "What two numbers multiply to -980 and add up to -979?"

The answer to your question is:

-980 and 1

Below we illustrate and prove that -980 and 1 multiply to -980 and add up to -979:

-980 × 1 = -980
-980 + 1 = -979

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

x² - 979x - 980 = 0

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

(x - 980 ) (x + 1)

To summarize, since -980 and 1 multiply to -980 and add up -979, you know that the following is true:

x² - 979x - 980 = (x - 980 ) (x + 1)
