Objectives: Standard 15.0 I will find the LCM (Least Common Multiple) of the given denominators I will simplify the rational expressions by using the LCM of the given denominators

Review 1 Important: When finding LCM, take the highest exponent of the same factor.

Review 2 Important: When finding LCM, multiply the factor even it is not a common factor for both given numbers.

Finding the Least Common Multiple

Practice from Textbook Textbook A44 Q.53-60

Objective Standard 15.0 I will use the LCM of the denominators to add and subtract rational expressions

Using the LCM to Add Rational Expressions

Using the LCM to Subtract Rational Expressions

Practice from Textbook Textbook A44 Q.61-68 Once you are done, you can continue to work on Textbook A44 Q.69-72
