Chapter 7
  • Section 3
  • Binomial Radical Expressions

Adding and Subtracting Radical Expressions
  • You can only add/subtract like radicals
  • Like radicals have the same index and the same
    radicand
  • If you dont have like radicals see if the
    radicals can be simplified to match

Multiplying and Dividing Radical Expressions
  • When multiplying two binomials ( )( ) use
    FOIL (or distributive property)
