Lesson 8: Multiplying & Squaring Binomials Radical Expressions

At the end of class today you should be able to: Multiply binomials using FOIL Expand a squared binomial using the appropriate formula Use radical expression terminology correctly Determine whether an algebraic expression containing radicals is simplified or not Simplify radical expressions, products of radicals and quotients of radicals containing real numbers

FOIL First – Outer – Inner – Last Simplify:

Squaring a Binomial Formulas: Simplify:

Radical Terminology

A radical expression is simplified when… The radicand contains no factors that are perfect squares (excluding “1”) The radicand contains no fractions No radicals appear in the denominator Only one radical sign is needed.

Two rules for radicals
