$x^3 - 64x \\ \\ gcf = x \\ \\ x( \frac{x^3}{x} + \frac{-64x}{x} ) \\ \\ x(x^2 - 64) \\ \\ x(x^2 - 8^2) \\ \\ x(x + 8)(x - 8) \\ \\$

The final result is: C) x(x - 8)(x + 8).

ok so first we divide 54 by 6 and get 9 so now we now that we have two sixes and two 9s for our edges now we add 6 plus 9 plus 6 plus 9 and we get 30
