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:

-10 and 98

Below we illustrate and prove that -10 and 98 multiply to -980 and add up to 88:

-10 × 98 = -980
-10 + 98 = 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 - 10 ) (x + 98)

To summarize, since -10 and 98 multiply to -980 and add up 88, you know that the following is true:

x² + 88x - 980 = (x - 10 ) (x + 98)
