What two numbers multiply to 392 and add up to -198?

Here we answer the question: "What two numbers multiply to 392 and add up to -198?"

The answer to your question is:

-196 and -2

Below we illustrate and prove that -196 and -2 multiply to 392 and add up to -198:

-196 × -2 = 392
-196 + -2 = -198

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

x² - 198x + 392 = 0

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

(x - 196 ) (x - 2)

To summarize, since -196 and -2 multiply to 392 and add up -198, you know that the following is true:

x² - 198x + 392 = (x - 196 ) (x - 2)
