What two numbers multiply to -980 and add up to 191?

Here we answer the question: "What two numbers multiply to -980 and add up to 191?"

The answer to your question is:

-5 and 196

Below we illustrate and prove that -5 and 196 multiply to -980 and add up to 191:

-5 × 196 = -980
-5 + 196 = 191

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

x² + 191x - 980 = 0

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

(x - 5 ) (x + 196)

To summarize, since -5 and 196 multiply to -980 and add up 191, you know that the following is true:

x² + 191x - 980 = (x - 5 ) (x + 196)
