Question

Find all the numbers for which the rational expression is undefined:
-6/19w

Answer 1

w = 0

Answer 2

zero

Answer 3

Assuming it's \[\large -\frac{6}{19w}\], since you cannot divide by zero, this means that the denominator 19w cannot be equal to zero.

So 19w = 0 means that w = 0


So w = 0 makes the expression undefined.
