What two numbers multiply to 408 and add up to -206?

Here we answer the question: "What two numbers multiply to 408 and add up to -206?"

The answer to your question is:

-204 and -2

Below we illustrate and prove that -204 and -2 multiply to 408 and add up to -206:

-204 × -2 = 408
-204 + -2 = -206

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

x² - 206x + 408 = 0

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

(x - 204 ) (x - 2)

To summarize, since -204 and -2 multiply to 408 and add up -206, you know that the following is true:

x² - 206x + 408 = (x - 204 ) (x - 2)
