To identify the items as expressions or equations:
1. **2x^3 - 4x^2** - This is an **expression** because it does not contain an equality sign.
2. **x = 3x^2 - 4** - This is an **equation** because it includes an equality sign (the "=" sign).
3. **5x = 25** - This is also an **equation** because it has an equality sign.
4. **3x + 2π** - This is an **expression** because it does not contain an equality sign.
So the categorization is as follows:
- **Expression**: 2x^3 - 4x^2, 3x + 2π
- **Equation**: x = 3x^2 - 4, 5x = 25
