Both the product and the domain match. $\displaystyle\frac{{{{\left({x}-{2}\right)}}^{{2}}}}{{{3}{x}}}\cdot\frac{{{6}{{x}}^{{2}}}}{{{x}-{2}}}={2}{{x}}^{{2}}-{4}{x}\usepackage{cmbright}\Huge\$ , and $\displaystyle{x}={0}\usepackage{cmbright}\Huge\$ and $\displaystyle{x}={2}\usepackage{cmbright}\Huge\$ are excluded from the domain because those values for x yield a denominator of 0.
