What two numbers multiply to -666 and add up to -65?

Here we answer the question: "What two numbers multiply to -666 and add up to -65?"

The answer to your question is:

-74 and 9

Below we illustrate and prove that -74 and 9 multiply to -666 and add up to -65:

-74 × 9 = -666
-74 + 9 = -65

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

x² - 65x - 666 = 0

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

(x - 74 ) (x + 9)

To summarize, since -74 and 9 multiply to -666 and add up -65, you know that the following is true:

x² - 65x - 666 = (x - 74 ) (x + 9)
