(x+2)/(x) is a rational expression. Its domain is all real numbers except square

To determine the domain of the rational expression \(\frac{x+2}{x}\), we need to identify the values of \(x\) that make the denominator zero, since division by zero is undefined.<br /><br />The denominator of the expression is \(x\). We set the denominator equal to zero and solve for \(x\):<br /><br />\[ x = 0 \]<br /><br />Therefore, the rational expression \(\frac{x+2}{x}\) is undefined when \(x = 0\).<br /><br />Thus, the domain of the rational expression \(\frac{x+2}{x}\) is all real numbers except \(x = 0\).<br /><br />So, the answer is:<br />\[ \boxed{0} \]
