Find the real values of z for which the given expression is undefined
2z/2z^2+z
-----
Factor:
(2z)/(z(2z+1))
---
Undefined with the denominator = 0.
---
Note: 0/0 is said to be undetermined because it can be any value.
(2z)/0 is said to be undefined because it can be no value.
----
Your problem is "undefined" when z = -1/2.
It is undetermined when z = 0
