Distributive Property and Simplification

The video tutorial explains the distributive property, which involves multiplying a single term by each term inside a set of parentheses. It provides two examples: one with a trinomial and negative numbers, and another with variables. The tutorial demonstrates how to simplify expressions by distributing terms and combining like terms, emphasizing the importance of understanding the process to simplify algebraic expressions effectively.

What is the basic formula of the distributive property?

• a - b = b - a

• a(b - c) = ab - ac

• a(b + c) = ab + ac

• a + b = b + a
