1. **State the problem:**
Match each algebraic expression to its corresponding graph or simplified form.
2. **Expressions given:**
- $x(x - 4)$
- $4x(x + 1)$
- $-4x^2 - 2x + 5$
3. **Simplify each expression:**
- For $x(x - 4)$, use distributive property:
$$x(x - 4) = x^2 - 4x$$
- For $4x(x + 1)$, distribute $4x$:
$$4x(x + 1) = 4x^2 + 4x$$
- The third expression is already simplified: $-4x^2 - 2x + 5$
4. **Summary of simplified forms:**
- $x^2 - 4x$
- $4x^2 + 4x$
- $-4x^2 - 2x + 5$
5. **Explanation:**
Each expression is a quadratic polynomial. The first two are factored forms expanded to standard form. The third is already in standard form.
6. **Matching:**
- $x(x - 4)$ matches $x^2 - 4x$
- $4x(x + 1)$ matches $4x^2 + 4x$
- $-4x^2 - 2x + 5$ remains as is
This completes the matching of expressions to their simplified forms or graphs.
