Simplifying Complex Fractions

The video tutorial explains how to simplify a complex fraction using method two. It begins by finding the least common denominator (LCD) of the fractions in the numerator and denominator. The tutorial then demonstrates multiplying the entire complex fraction by the LCD to simplify it. The process involves clearing parentheses, combining like terms, and checking if further simplification is possible. The final result is a simplified rational expression. The tutorial emphasizes the importance of using parentheses and provides guidance on entering the expression using a keyboard or equation tool.

What is the first step in Method Two for simplifying complex fractions?

• Multiply the numerator and denominator by the LCD

• Find the least common denominator of the fractions

• Factor the numerator and denominator

• Combine like terms
