She's taking, let's see. So this seems off. She is assuming that the derivative of a product is equal to the product of the derivatives. That is not the case. And especially, and it's, if you have a constant here, there's actually a much simpler way of thinking about it, frankly, the way that Avery thought about it. Avery had made a mistake at step one. But this is actually going to be equal to the derivative of a constant times an expression is equal to the same thing as the constant times the derivative of the expression.
