  1. Warm Up #13

  2. Warm Up #13: 2x2 + 4x - 6 4x + 1 x2 – 6x +36

  3. Complex Rational Expressions Fractions inside of fractions are a NO - NO And must be simplified.

  4. Steps • Find the LCD of the numerator and denominator • Multiply the complex rational expression by the LCD/LCD (so its equivalent to multiplying by 1) • Simplify (factor and cross out common factors)

  5. Complex Rational Expressions Example 1:

  6. Example 2:

  7. Example 3:

  8. Example 4:

  9. Example 5: You try

  10. Example 6: You try 8/5

  11. Short Cut • If there are 2 terms or more on either the numerator or denominator you must multiply by the LCD/LCD • However, if there is only 1 term on the numerator and 1 term on the denominator then you can divide fractions (which means multiply by the reciprocal)

  12. Example 7:
