What two numbers multiply to 197 and add up to -198?

Here we answer the question: "What two numbers multiply to 197 and add up to -198?"

The answer to your question is:

-197 and -1

Below we illustrate and prove that -197 and -1 multiply to 197 and add up to -198:

-197 × -1 = 197
-197 + -1 = -198

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

x² - 198x + 197 = 0

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

(x - 197 ) (x - 1)

To summarize, since -197 and -1 multiply to 197 and add up -198, you know that the following is true:

x² - 198x + 197 = (x - 197 ) (x - 1)
