Correct. When $\displaystyle{x}={0}\usepackage{cmbright}\Huge\$ , the expression becomes $\displaystyle\frac{{{0}+{3}}}{{0}}\div\frac{{{7}{\left({0}\right)}}}{{{\left({0}-{2}\right)}}^{{2}}}\usepackage{cmbright}\Huge\$ ; when $\displaystyle{x}={2}\usepackage{cmbright}\Huge\$ , the expression becomes $\displaystyle\frac{{{2}+{3}}}{{2}}\div\frac{{{7}{\left({2}\right)}}}{{{\left({2}-{2}\right)}}^{{2}}}=\frac{{5}}{{2}}\div\frac{{14}}{{0}}\usepackage{cmbright}\Huge\$ . Since division by 0 is undefined, these values must be excluded from the domain of the expression.
