Here we answer the question: "What two numbers multiply to 198 and add up to -199?"

The answer to your question is:

-198 and -1

Below we illustrate and prove that -198 and -1 multiply to 198 and add up to -199:

-198 × -1 = 198
-198 + -1 = -199

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

x² - 199x + 198 = 0

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

(x - 198 ) (x - 1)

To summarize, since -198 and -1 multiply to 198 and add up -199, you know that the following is true:

x² - 199x + 198 = (x - 198 ) (x - 1)
