What two numbers multiply to -980 and add up to 29?

Here we answer the question: "What two numbers multiply to -980 and add up to 29?"

The answer to your question is:

-20 and 49

Below we illustrate and prove that -20 and 49 multiply to -980 and add up to 29:

-20 × 49 = -980
-20 + 49 = 29

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

x² + 29x - 980 = 0

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

(x - 20 ) (x + 49)

To summarize, since -20 and 49 multiply to -980 and add up 29, you know that the following is true:

x² + 29x - 980 = (x - 20 ) (x + 49)
