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

x² - 11x - 12 = 0

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

(x - 12 ) (x + 1)

To summarize, since -12 and 1 multiply to -12 and add up -11, you know that the following is true:

x² - 11x - 12 = (x - 12 ) (x + 1)
