  1. Adding and subtracting rational expressions: To add or subtract rational expressions use the addition property:

  2. If the expressions have the same (common) denominator, add or subtract the numerators, keep the same denominator, and simplify the result.

  3. To add or subtract fractions with different denominators find the least common denominator (LCD), change each fraction so that it has that denominator then add or subtract.

  4. Add : • LCD = • change each fraction to LCD • add/subtract • simplify

  5. Add : • LCD = • change each fraction to LCD • add/subtract • simplify

  6. Add : • LCD = • change each fraction to LCD • add/subtract • simplify

  7. Simplify : Grab a white board for some practice.

  8. Do the operations and simplify:
