This is your first question

The critical points are the points where the derivative is zero or fails to exist due to any reason.

In this case on differentiating we find the derivative as 10(x-1)/(x-2)1/3

This derivative is zero at x=1 and not defined at x=2 therefore these two are the critical points.
