Determine the factors of x2 - 6x - 8.

Prime

(x + 4) (x - 2)

(x - 4) (x + 2)

(x + 8) (x - 1)

Cannot be factored

x² - 6x - 8

x² breaks down into x and x

8 breaks down into 1 and 8, 2 and 4, 4 and 2, or 8 and 1.

(x+4) (x-2) = x² + 2x - 8

(x-4) (x+2) = x² - 2x - 8

(x-4) (x-2) = x² - 6x + 8

(x+4) (x+2) = x² + 6x + 8
