What two numbers multiply to 816 and add up to -208?

Here we answer the question: "What two numbers multiply to 816 and add up to -208?"

The answer to your question is:

-204 and -4

Below we illustrate and prove that -204 and -4 multiply to 816 and add up to -208:

-204 × -4 = 816
-204 + -4 = -208

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

x² - 208x + 816 = 0

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

(x - 204 ) (x - 4)

To summarize, since -204 and -4 multiply to 816 and add up -208, you know that the following is true:

x² - 208x + 816 = (x - 204 ) (x - 4)
