What two numbers multiply to -980 and add up to 133?

Here we answer the question: "What two numbers multiply to -980 and add up to 133?"

The answer to your question is:

-7 and 140

Below we illustrate and prove that -7 and 140 multiply to -980 and add up to 133:

-7 × 140 = -980
-7 + 140 = 133

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

x² + 133x - 980 = 0

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

(x - 7 ) (x + 140)

To summarize, since -7 and 140 multiply to -980 and add up 133, you know that the following is true:

x² + 133x - 980 = (x - 7 ) (x + 140)
