📌 **WHAT'S INCLUDED:**

### **1. Visual Guided Notes — 6 Core Sections**

**§1 Polynomial Operations:** Adding, subtracting, multiplying, and dividing polynomials (long division & synthetic division).

**§2 Factoring Strategies:** GCF, grouping, trinomial factoring (a=1 and a≠1), difference of squares, and sum/difference of cubes, plus a factoring flowchart.

**§3 End Behavior & Graphing Polynomials:** Degree, leading coefficient, end behavior notation, zeros, and sketching polynomial graphs (degree 2–5).

**§4 Remainder & Factor Theorems:** Evaluating polynomials, applying the Remainder Theorem, using the Factor Theorem, and finding all zeros (including the Rational Root Theorem).

**§5 Rational Expressions:** Simplifying, multiplying, dividing, and adding/subtracting with unlike denominators.

**§6 Graphing Rational Functions:** Vertical, horizontal, and oblique asymptotes, point discontinuities (holes), and sketching rational graphs.

### **2. Practice & Activities**

**50 Polynomial Operations Practice Problems:** Three difficulty levels—Basic, Intermediate, and Advanced.

**Graphing Polynomial Functions Activity:** Analyzing and sketching polynomials with and without a calculator.

**40 Rational Expressions Drill Set:** Four targeted operations—simplify, multiply, divide, and add/subtract.

**Asymptotes & Holes Discovery Activity:** A guided exploration for students to discover rules for vertical/horizontal asymptotes and holes.

**Real-World Modeling Mini-Project:** **“The Custom Cardboard Box”** volume optimization project applying polynomial functions.

### **3. Assessments & Answer Keys**
