Polynomials (Chapters 6 & 7)
Lesson 4: Adding/Subtracting Polynomials (7.2 & 7.3)
Learning Goals of Lesson 4
By the end of this lesson, I can:
-add and subtract two or more polynomials
-first expand brackets then add and subtract polynomials
-apply adding/subtracting polynomials to perimeter problems
Video 1: Add/Subtract Polynomials Using Algebra Tiles
Video 2: How to Add and Subtract Polynomials
Video 3: Adding and Subtracting Polynomials
Video 4: Multiply Then Add/Subtract Polynomials
Video 5: Find Perimeter of a Triangle Using Polynomials
Always separate each side length with brackets when adding or subtracting!
Perimeter = (2r² + 3r) + (5r + 5) + (r³ + r² + 3)
