That is factored already.

First distribute the negative sign:
(-x - 2)(x - 20)²
Next, square the (x - 20):
(-x -2)(x² - 40x + 400)
Next, multiply the (-x - 2) through the rest of the formula:
-x³ + 40x² - 2x² - 400x + 80x - 800
Finally, combine like terms:
-x³ + 38x² - 320x - 800
Edit: Steve is right. What I did was "reverse factoring."

factor expression -(x+2) (x-20)^2
expand: -x^3 + 38x^2 - 320x - 800
