In arithmetic, an inequality is a press release that two expressions should not equal. Undefined values in an inequality are values that make one or each of the expressions undefined. To search out the undefined values in an inequality, we have to discover the values that make the denominator of both expression equal to zero.
For instance, take into account the inequality $frac{x-1}{x+2} > 0$. The denominator of the left-hand facet is $x+2$, which is the same as zero when $x=-2$. Subsequently, the undefined worth on this inequality is $x=-2$.
