Distributing and Simplifying Expressions

The video tutorial explains how to simplify algebraic expressions by distributing and combining like terms. It covers two examples: the first involves distributing positive and negative numbers to clear parentheses and combining like terms to simplify the expression to 5x + 61. The second example demonstrates distributing negative numbers and dropping parentheses to simplify the expression to -x - 14. The tutorial emphasizes understanding the distribution process and combining like terms to achieve the final simplified expressions.
