Giải thích các bước giải:
`(x-3)^2=9`
`=>`\(\left[ \begin{array}{l}(x-3)^2=3^2\\(x-3)^2=(-3)^2\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}x-3=3\\x-3=-3\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}x=3+3\\x=-3+3\end{array} \right.\)
`=>`\(\left[ \begin{array}{l}x=6\\x=0\end{array} \right.\)
