What two numbers multiply to 792 and add up to -78?

Here we answer the question: "What two numbers multiply to 792 and add up to -78?"

The answer to your question is:

-66 and -12

Below we illustrate and prove that -66 and -12 multiply to 792 and add up to -78:

-66 × -12 = 792
-66 + -12 = -78

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

x² - 78x + 792 = 0

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

(x - 66 ) (x - 12)

To summarize, since -66 and -12 multiply to 792 and add up -78, you know that the following is true:

x² - 78x + 792 = (x - 66 ) (x - 12)
