Find the critical numbers of the function
The Attempt at a Solution
Here, I stuck. If I continue with this equation, my answers are x1=0 and x2 is less than 1.
But if I try to get rid of the root in order to find the critical points by doubling the both sides of equation, my answer is x1=0, x2 not equal to 1.
These are quite different answers. Please help me out with the problem.
