Distributive Property and Simplification

The video tutorial explains the distributive property in algebra, demonstrating how to simplify expressions by multiplying each term inside parentheses by a factor outside. Two examples are provided: one with positive terms and another with negative terms, illustrating the process of simplification and the handling of negative signs. The tutorial emphasizes understanding the concept to reduce the amount of work shown in calculations.

What is the distributive property formula?

• a + b + c = a * b * c

• a * (b - c) = a * b - c

• a + (b * c) = a + b * c

• a * (b + c) = a * b + a * c
