I think that the number of times you drink all the water in your bottle is independent, because the number of liters you drink depends on how much there is.
Independent- the number of times you drink all the water in your bottle
Dependent- the number of liters you drink
2x² - 128
2(x² - 64), but (x² - 64) = x² - 8² (difference of 2 squares),[a²-b²=(a-b)(a+b)]
2(x² - 64) = 2(x² - 8²) = 2(x-8)(x+8)
