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

x² - 28x + 27 = 0

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

(x - 27 ) (x - 1)

To summarize, since -27 and -1 multiply to 27 and add up -28, you know that the following is true:

x² - 28x + 27 = (x - 27 ) (x - 1)
