Understanding Like Terms and Simplifying Polynomials

The video tutorial explains how to identify and combine like terms to simplify polynomials. It begins with an introduction to like terms, which are terms with the same variable factors. The tutorial provides examples of identifying like terms and demonstrates the process of combining them by adding or subtracting coefficients. It also includes a detailed example of simplifying a polynomial by combining like terms, resulting in a simplified expression.

What defines like terms in a polynomial?

• Terms with different exponents

• Terms with the same coefficients

• Terms with the same variable factors and exponents

• Terms with different variables
