🏭 Part 1: Factory Setup & Key Concepts

Welcome to the Polynomial Factory! Your team runs a manufacturing company where products are represented by polynomials. You'll need to master polynomial operations to manage inventory, fulfill orders, and expand production.

1. Key Concept Review: Circle the like terms in each polynomial expression:

a) 3x² + 5x - 2x² + 7x + 1

b) 4x³ - x + 6x² + 2x - 9 + x³

2. Combining Like Terms: When adding polynomials, we combine terms with the same _____________ and same _____________.

3. Distributive Property: To multiply (x + 3)(x - 2), we distribute each term in the first polynomial to each term in the second. Show this process:

📦 Part 2: Factory Operations

Scenario: Your factory produces three main product lines represented by these polynomials:

• Product A: 2x² + 3x - 1

• Product B: x² - 2x + 5

• Product C: 3x - 4

4. Inventory Addition: You receive new shipments of Products A and B. Find the total inventory by adding the polynomials:

(2x² + 3x - 1) + (x² - 2x + 5) = _________________________

5. Quality Control: You discover some damaged goods and must subtract them from inventory. Calculate:

(3x² + 7x + 2) - (x² + 4x - 3) = _________________________

6. Production Expansion: To meet increased demand, you multiply your Product C production by (x + 2). Calculate the new production level:

(3x - 4)(x + 2) = _________________________

7. Complex Order: A major client orders the following combination. Simplify completely:

2(x² + 3x - 1) + 3(2x² - x + 4) - (x² + 5x - 2)

8. Special Production Run: Calculate this advanced order:

(x + 3)(x² - 2x + 1) = _________________________

🤔 Part 3: Factory Analysis & Reasoning

9. Error Analysis: A new employee calculated (2x + 1)(x - 3) = 2x² - 3. Explain what went wrong and show the correct solution:

10. Real-World Connection: Describe a real manufacturing situation where you might need to subtract one polynomial from another:

11. Strategy Reflection: What is one key strategy that helps you avoid mistakes when multiplying polynomials?

12. Challenge Problem: Your factory's profit can be modeled by (x² + 4x - 5) and costs by (2x² - 3x + 7). Write and simplify an expression for net income (profit - costs):
