Ta có:
\(\left(2x-3\right)\left(6-2x\right)=0\)
\( \Rightarrow \left[ {\begin{array}{*{20}{c}} {2x - 3 = 0}\\ {6 - 2x = 0} \end{array}} \right. \Rightarrow \left[ {\begin{array}{*{20}{c}} {2x = 3}\\ {2x = 6} \end{array}} \right. \Rightarrow \left[ {\begin{array}{*{20}{c}} {x = \frac{2}{3}}\\ {x = 3} \end{array}} \right.\)
