What two numbers multiply to 398 and add up to -201?

Here we answer the question: "What two numbers multiply to 398 and add up to -201?"

The answer to your question is:

-199 and -2

Below we illustrate and prove that -199 and -2 multiply to 398 and add up to -201:

-199 × -2 = 398
-199 + -2 = -201

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

x² - 201x + 398 = 0

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

(x - 199 ) (x - 2)

To summarize, since -199 and -2 multiply to 398 and add up -201, you know that the following is true:

x² - 201x + 398 = (x - 199 ) (x - 2)
