What two numbers multiply to 198 and add up to -69?

Here we answer the question: "What two numbers multiply to 198 and add up to -69?"

The answer to your question is:

-66 and -3

Below we illustrate and prove that -66 and -3 multiply to 198 and add up to -69:

-66 × -3 = 198
-66 + -3 = -69

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

x² - 69x + 198 = 0

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

(x - 66 ) (x - 3)

To summarize, since -66 and -3 multiply to 198 and add up -69, you know that the following is true:

x² - 69x + 198 = (x - 66 ) (x - 3)
