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:

18 and 37

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

18 × 37 = 666
18 + 37 = 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 + 18 ) (x + 37)

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

x² + 55x + 666 = (x + 18 ) (x + 37)
