  2. Part 1: Addition with Unlike Denominators The pattern…… = …..is useful for adding rational expressions with different denominators.

  3. Question One: • Step one: Use the pattern for adding rational expressions- • Step two: Factor to look for common factors - • Step Three: Simplify- • You Are Done!

  4. Part 2: Subtraction with Unlike Denominators To subtract expressions with unlike denominators, use the pattern……. -

  5. Question Two: • Step one: Use the pattern for subtracting rational expressions- • Step two: • Step three: • Step four: • Step five: • Answer:

  6. Part 3: Using Least Common Multiples To find the LCM of two or more algebraic expressions, • Factor each expression. • Form the product using each factor the greatest number of times it occurs.

  7. Question 3: Find the LCM of 8 and -12x 8=2*2*2*x*x*y*y -12x= -2*2*3*x*y*y*y LCM= 2*2*2*3*x*x*y*y*y =24
