Trig help. Simplifying fraction with radicals.

The fraction is:
(1-(sqrt3)/3) / (1+(sqrt3)/3)
The correct answer is 2-(sqrt3) I just have no idea how that was obtained.

[-1 + (sqrt3 / 3)] / [1 - (-1) x (sqrt3 / 3)] = [-1 + (sqrt(3) / 3)] / [1 + (sqrt(3) / 3)] = 3[-1 + (sqrt(3) / 3)] / 3[1 + (sqrt(3) / 3)] = [-3 + sqrt(3)] / [3 + sqrt(3)] = [-3 + sqrt(3)][sqrt(3) - 3)] / [sqrt(3) + 3][sqrt(3) - 3] = [(sqrt(3) - 3)(sqrt(3) - 3)] / [sqrt(3)^2 + 3sqrt(3) - 3sqrt(3) - 9] = [(sqrt(3))^2 - 3sqrt(3) - 3sqrt(3) + (-3)^2] / [3 - 9] = [3 - 6sqrt(3) + 9] / -6 = [12 - 6sqrt(3)] / -6 = (12 / -6) + (-6sqrt(3) / -6) = -2 + sqrt(3)
