Answer:

The solution is x = 2 or x = 3  

Step-by-step explanation:

we have to find the solution of the equation

[tex] x=2+\sqrt{(x-2)}[/tex]

[tex]x=2+\sqrt{(x-2)}\\ \\x-2=\sqrt{x-2}\\\\\text{Squaring on both sides }\\\\(x-2)^2=x-2\\\\x^2+4-4x=x-2\\\\x^2-5x+6=0\\\\x^2-2x-3x+6=0\\\\x(x-2)-3(x-2)=0\\\\(x-2)(x-3)=0\\\\x=2\text{ or }x=3[/tex]

Hence, correct option is x = 2 or x = 3
