To solve this equation, we can start by isolating the square root terms on one side of the equation.

căn x - 2 căn x - 1 = căn x - 1 - 1

First, let's combine the square root terms on the left side of the equation:

căn x - 2 căn x - 1 = căn x - 2

Now, let's simplify the right side of the equation:

căn x - 2 = căn x - 2

Since both sides of the equation are equal, we can conclude that the equation is true for all values of x.
