What two numbers multiply to -992 and add up to 991?

Here we answer the question: "What two numbers multiply to -992 and add up to 991?"

The answer to your question is:

-1 and 992

Below we illustrate and prove that -1 and 992 multiply to -992 and add up to 991:

-1 × 992 = -992
-1 + 992 = 991

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

x² + 991x - 992 = 0

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

(x - 1 ) (x + 992)

To summarize, since -1 and 992 multiply to -992 and add up 991, you know that the following is true:

x² + 991x - 992 = (x - 1 ) (x + 992)
