Sec 1.2 –Revisiting Quadratics (Review) Simplifying Radicals Name: PRODUCTRULE: QUOTIENTRULE: √ ∙ √ √ Example: √10 √ Example: √10 ∙ √ √ √5 More directly, when determining a product or quotient of radicals and the indices (the small number in front of the radical) are the same then you can rewrite 2 radicals as 1 or 1 radical as 2. Simplify by rewriting the following using only one radical sign (i.e. rewriting 2 radicals as 1). 1. √7 ∙ 2 2. √ √ Simplify by rewriting the following using multiple radical sign (i.e. rewriting 1 radical as 2). 3. 4.
