What two numbers multiply to -666 and add up to 331?

Here we answer the question: "What two numbers multiply to -666 and add up to 331?"

The answer to your question is:

-2 and 333

Below we illustrate and prove that -2 and 333 multiply to -666 and add up to 331:

-2 × 333 = -666
-2 + 333 = 331

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

x² + 331x - 666 = 0

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

(x - 2 ) (x + 333)

To summarize, since -2 and 333 multiply to -666 and add up 331, you know that the following is true:

x² + 331x - 666 = (x - 2 ) (x + 333)
