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:

9 and 74

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

9 × 74 = 666
9 + 74 = 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 + 9 ) (x + 74)

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

x² + 83x + 666 = (x + 9 ) (x + 74)
