Differentiate (x-2)^2

Answer is 2x - 4. This is found by following the standard differentiation procedure of n(ax-b)^n-1 where n was the previous power and a and b are the value inside the bracket. This means that it first goes to 2(x-2) before multiplying out to the final answer of 2x - 4. The chain rule does not need to be applied as the x is not to the power of anything.
