What two numbers multiply to 666 and add up to -55?

Here we answer the question: "What two numbers multiply to 666 and add up to -55?"

The answer to your question is:

-37 and -18

Below we illustrate and prove that -37 and -18 multiply to 666 and add up to -55:

-37 × -18 = 666
-37 + -18 = -55

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

x² - 55x + 666 = 0

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

(x - 37 ) (x - 18)

To summarize, since -37 and -18 multiply to 666 and add up -55, you know that the following is true:

x² - 55x + 666 = (x - 37 ) (x - 18)
