Adding Polynomials: Key Concepts and Techniques

This video tutorial teaches how to add polynomials by focusing on like terms. It explains that like terms have the same variable raised to the same power and provides examples of both like and unlike terms. The video demonstrates adding like terms by summing their coefficients and shows how to add binomials and trinomials in standard form. Additionally, it introduces the stack and add method as an alternative approach to adding polynomials.

What is the first step in adding polynomials?

• Multiplying the variables

• Identifying like terms

• Dividing the constants

• Subtracting the coefficients
