How do you go from setting the derivative of y to a critical point of x=0. Please show those steps. I am getting 1. Thanks

I was struggling with this too, then after some toil remembered that critical numbers also include where the slope is undefined. The x=1 we kept getting is valid. Though, It is doubled up for evaluation by also being the endpoint on our closed interval. x=0 is where the solution is undefined, which only becomes apparent after combining the fraction!
