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

The answer to your question is:

-997 and -1

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

-997 × -1 = 997
-997 + -1 = -998

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

x² - 998x + 997 = 0

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

(x - 997 ) (x - 1)

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

x² - 998x + 997 = (x - 997 ) (x - 1)
