\qquad\qquad\huge\underline{{\sf Answer}}

Let's evaluate ~


\qquad \sf&nbsp; \dashrightarrow \: \sqrt{{x}^(2) - 6x + 9 }


\qquad \sf&nbsp; \dashrightarrow \: \sqrt{{x}^(2) - 3x - 3x+ 9 }


\qquad \sf&nbsp; \dashrightarrow \: \sqrt{{x(}^{} x- 3) - 3(x - 3) }


\qquad \sf&nbsp; \dashrightarrow \: √(( x- 3) (x - 3) )


\qquad \sf&nbsp; \dashrightarrow \: \sqrt{( x- 3) {}^(2) }


\qquad \sf&nbsp; \dashrightarrow \: {( x- 3) {}^{} }

I hope you understood the procedure ~ let me know if you have doubts ~
