So you bring the two times the six to get 12. So minus 12 x to the, well two minus one is one power, so that's the same thing as 12x. And then plus the derivative of x is just one. That's just going to be one. And if you view this as x to the first power, we're just bringing the one out front and decrementing the one. So we have one times x to the zero power, which is just one. And then the derivative of a constant here is just going to be zero.
