In arithmetic, an inequality is an announcement that two expressions should not equal. Undefined values in an inequality are values that make one or each of the expressions undefined. To seek 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 aspect is $x+2$, which is the same as zero when $x=-2$. Subsequently, the undefined worth on this inequality is $x=-2$.
