Question
**Problem Statement:**

Find and classify the critical points of \( z = (x^2 - 3x)(y^2 - 4y) \).

**Classification:**

- **Local maximums:**
  
- **Local minimums:**
  
- **Saddle points:**

For each classification, enter a list of ordered pairs \((x, y)\) where the maximum, minimum, or saddle occurs. Enter DNE (Does Not Exist) if there are no points for a classification.
