  7. Lesson 11-2A Add or subtract radicals

  8. Recall: Adding or subtracting like terms: ex: 10x – 2x + x = ex: 3x + 5y + 4x = 9x 7x + 5y Today: Adding or subtracting radicals Look for like radicands ex: ex: 3 2 + 5 2 = 8 2

  9. Simplify: 6 5 + 2 5 – 1 5 = 7 5

  10. Simplify: -3 6 + 4 2 + 7 6 = 4 6 + 4 2
