Let's identify each of the provided items as either an expression or an equation:

1. **2x³ - 4x²**: This is an **expression** because it does not have an equality sign.

2. **x = 3x² - 4**: This is an **equation** because it contains an equality sign (=).

3. **5^x = 25**: This is also an **equation** because it contains an equality sign (=).

4. **3x + 2π**: This is an **expression** because it does not have an equality sign.

In summary:
- 2x³ - 4x²: Expression
- x = 3x² - 4: Equation
- 5^x = 25: Equation
- 3x + 2π: Expression
