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:

-222 and -3

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

-222 × -3 = 666
-222 + -3 = -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 - 222 ) (x - 3)

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

x² - 225x + 666 = (x - 222 ) (x - 3)
