  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. Do the operations and simplify the result:

  4. 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.

  5. Simply stated, the LCD is the least number (expression) that all denominators will divide into evenly.

  6. To find the LCD • factor each denominator • write the different factors • give each factor the highest power to which it occurs • multiply the results

  7. Factor each write each factor give each highest exponent multiply results (y+4)(y-4) and (y-4)² (y+4)(y-4) (y+4)(y-4)² (y+4)(y-4)² Find the LCD for y²-16 and y²-8y+16

  8. Find the LCD of :

  9. Find the LCD of :
