What two numbers multiply to -666 and add up to -19?

Here we answer the question: "What two numbers multiply to -666 and add up to -19?"

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 -19:

-37 × 18 = -666
-37 + 18 = -19

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

x² - 19x - 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 -19, you know that the following is true:

x² - 19x - 666 = (x - 37 ) (x + 18)
