What two numbers multiply to 666 and add up to 225?

Here we answer the question: "What two numbers multiply to 666 and add up to 225?"

The answer to your question is:

3 and 222

Below we illustrate and prove that 3 and 222 multiply to 666 and add up to 225:

3 × 222 = 666
3 + 222 = 225

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

x² + 225x + 666 = 0

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

(x + 3 ) (x + 222)

To summarize, since 3 and 222 multiply to 666 and add up 225, you know that the following is true:

x² + 225x + 666 = (x + 3 ) (x + 222)
