Compare the determining of equivalent rational expressions to determining equivalent rational numbers.
(c)

Verify, with explanation, whether or not a given value is permissible for a given rational expression.
(d)

Develop, explain, and apply strategies for determining the non-permissible values of a rational expression.
(e)

Develop, explain, and apply strategies for simplifying rational expressions.
(f)

Explain why the non-permissible values of a simplified rational expression must be stated as those of the original rational expression.
(g)

Apply understanding of rational expressions to locate and correct errors in the simplification of a rational expression.
(h)

Develop, verify, explain, and apply strategies for adding, subtracting, multiplying, and dividing rational expressions, including the determination of non-permissible values.
(i)

Compare the performing of operations on rational expressions to performing the same operations on rational numbers.

McGraw-Hill Ryerson Pre-Calculus 11. Student Edition
The student text consists of four units. Each unit opens with a two-page spread. The first page introduces what the students will learn throughout the unit and the second page introduces the unit project. Throughout the chapters are project corner boxes that will assist students to gather information for their projects. Each unit culminates with the project wrap-up. The chapters include career information based on the skills that will be learned. Opportunities are provided for students to make connections between math and the real world or to make connections to what students already know or may be studying in other classes. The student resource includes a table of contents, an answer key, a glossary and an index.
