What two numbers multiply to 666 and add up to -83?

Here we answer the question: "What two numbers multiply to 666 and add up to -83?"

The answer to your question is:

-74 and -9

Below we illustrate and prove that -74 and -9 multiply to 666 and add up to -83:

-74 × -9 = 666
-74 + -9 = -83

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

x² - 83x + 666 = 0

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

(x - 74 ) (x - 9)

To summarize, since -74 and -9 multiply to 666 and add up -83, you know that the following is true:

x² - 83x + 666 = (x - 74 ) (x - 9)
