Find all numbers for which the rational expression is undefined.
-17/-18x

A rational expression is undefined when and only when its denominator is zero,
because division by zero is not defined.
%28-17%29%2F%28-18x%29 is undefined when and only when -18x=0
That only happens when highlight%28x=0%29
For any other value of x, -18x is not zero and the rational
expression %28-17%29%2F%28-18x%29 is defined (It has a value).
