Look at restrictions if there is a radical in the denominator of a fraction such as: You can also investigate imaginary numbers as ways to deal with domain restrictions that may occur when performing calculations with radicals. Resources Math 20-1 (McGraw-Hill Ryerson: sec 5.1) Supporting Assessment Glossary conjugates Two binomial factors whose product is the difference of two squares [Math – 20-1 (McGraw-Hill Ryerson: page 587)] entire radical - A radical with a coefficient of 1 [Math 20-2 (Nelson: page 515)] - A statement of equality between two expressions A general term that ultimately represents a number. An expression can consist of – numbers, variables and operations on these. extraneous root A number obtained in the process of solving an equation that does not – satisfy the equation like radicals Radicals with the same radicand and index [Math 20-1 (McGraw-Hill – Ryerson: page 273)] mixed radicals - A radical with a coefficient other than 1 Associates two or more members of a with one of the members of the set. The basic – operations in mathematics are addition, subtraction, multiplication, division and exponentiation. - Includes radical sign, radical index and radicand. – – n – x – radical equation An equation with a variable within a radicand – rationalize A procedure for converting to a rational number without changing the value of – the expression [Math 20-1 (McGraw-Hill Ryerson: page 590)]
