What two numbers multiply to -979 and add up to 978?

Here we answer the question: "What two numbers multiply to -979 and add up to 978?"

The answer to your question is:

-1 and 979

Below we illustrate and prove that -1 and 979 multiply to -979 and add up to 978:

-1 × 979 = -979
-1 + 979 = 978

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

x² + 978x - 979 = 0

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

(x - 1 ) (x + 979)

To summarize, since -1 and 979 multiply to -979 and add up 978, you know that the following is true:

x² + 978x - 979 = (x - 1 ) (x + 979)
