Lesson Plan
Perform rational expression operations
Goals / Objectives
Multiply and divide rational expressions by multiplying numerators and denominators (or multiplying by the reciprocal), simplifying by canceling common polynomial factors
Add and subtract rational expressions with the same denominator by combining numerators
Add and subtract rational expressions with different denominators by finding the least common denominator (LCD) and building equivalent fractions
State and apply domain restrictions: identify x-values that make any denominator zero and must be excluded
Explain the analogy between rational number arithmetic and rational expression arithmetic, using this to justify each operation
