  • 3. You can add or subtract radicalslike monomials. You can alsosimplify radicals by using theFOIL method of multiplyingbinomials.Ex: (3 6 − 2 3)(4 + 3)Let us try one.
  • 4. (3 6 − 2 3)(4 + 3)3 6F⋅4 + 3 6O⋅ 3 − 2 3I⋅ 4 − 2 3L⋅ 312 6 + 3 32⋅ 2 − 8 3 − 2 ⋅312 6 + 9 2 − 8 3 − 6Since there are no like terms, youcan not combine.
  • 5. Lets do another one.(8 − 5 3)(8 + 5 3)8⋅ 8 + 8⋅ 5 3 − 5 3 ⋅8 − 5 3 ⋅5 364 + 40 3 − 40 3 − 25⋅ 364 − 75−11
