Page 3: Advanced Problems and Techniques
This page presents more complex problems involving rational functions and expressions, demonstrating advanced techniques for simplification and problem-solving.
Example: One problem involves simplifying the complex fraction x2+x+3 / 4x2+11x−3 - (2x2+1 - x+3) / (4x−14x+1).
The page also covers polynomial long division, which is useful when simplifying certain types of rational expressions.
Highlight: When dealing with complex fractions, it's often helpful to separate the expression into simpler parts and simplify each part individually before combining them.
The final section of the page includes problems that require a combination of techniques, such as factoring, finding common denominators, and simplifying.
Vocabulary: The domain of a rational function includes all real numbers except those that make the denominator equal to zero.
Throughout the page, emphasis is placed on carefully checking the domain restrictions for each step of the simplification process.
