  1. Thursday, January 16th Warm Up Simplify each expression 1. 2.

  2. EOCT QUESTION 4

  3. Homework Answers

  4. Name all Perfect squares from: 1-225

  5. How do you know when radicals are simplified?!?! 1. No radicand can have a perfect Square Factor 2. 3.

  6. Candy Toss

  7. Irrational or Rational 15.34

  8. Irrational or Rational 4.378….

  9. Irrational or Rational √36

  10. Irrational or Rational

  11. What is the largest perfect square factor? √98

  12. What is the largest perfect square factor? √75

  13. Today • Adding & Subtracting Radicals • Multiplying Radicals

  14. Let’s Think about it… Circle the terms you can combine? 4x, 4y, 6v, 7x, 6v, -3x, 5y Why can you combine these terms together? They’re like terms How do you combine these terms? Adding or subtracting

  15. Combining simple Radical Expressions Like radicals= same radicand You can COMBINElike radicals using addition and subtractions 3√6 + 8√6 3+8√6 11√6 In words Example

  16. Simplifying Before Adding or Subtracting Factor the radicands using perfect squares If the radicands are alike combine If the radicands are NOT alike then leave it  √12 + √24 √3(4) + √6(4) √3 √4 + √6 √4 2√3 + 2√6 Can’t combine; not like terms In words Example

  17. You Try! √45 - √20 4√12 + √27 √125b +3√20b -√45b

  18. Recipe for Multiplying Example: • Multiply what’s OUTSIDE • Multiply what’s INSIDE (Radicands) • Simplify the Radicand

  19. You Try

  20. Taking it a step further! Hints: Think of it as: 2x • 3x 2. Take it Step by Step Don’t forget to SIMPLIFY the radicand!! You Try!

  21. Distributing With Radical Expressions Example: • Distribute “outside” Radical to EVERYTHING inside the parantheses (Remember to talk to everyone at the party) • Simplify all radical Expressions

  22. You Try!!Remember to simply your radicand! 2. 1.
