What two numbers multiply to -998 and add up to 997?

Here we answer the question: "What two numbers multiply to -998 and add up to 997?"

The answer to your question is:

-1 and 998

Below we illustrate and prove that -1 and 998 multiply to -998 and add up to 997:

-1 × 998 = -998
-1 + 998 = 997

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

x² + 997x - 998 = 0

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

(x - 1 ) (x + 998)

To summarize, since -1 and 998 multiply to -998 and add up 997, you know that the following is true:

x² + 997x - 998 = (x - 1 ) (x + 998)
