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:

-9 and 74

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

-9 × 74 = -666
-9 + 74 = 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 - 9 ) (x + 74)

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

x² + 65x - 666 = (x - 9 ) (x + 74)
