Combining and Simplifying Expressions

The video tutorial explains how to simplify algebraic expressions by using the distributive property and combining like terms. It provides several examples, each demonstrating different scenarios: applying the distributive property, combining like terms, and recognizing when no simplification is possible. The tutorial classifies each step in the simplification process, helping learners understand the methodology behind simplifying expressions.
