Chapter 5 Topics – Algebraic Fractions
Click on any topic to expand and view its exercises. Each section includes step-by-step solutions and real-world applications.
5.1 – Simplification of Rational Expressions
Reduce to lowest terms, factor and cancel
This section covers reducing rational expressions to their lowest form by factoring and canceling common factors. You'll learn to simplify algebraic fractions with monomial, binomial, and trinomial numerators and denominators.
Simplification & lowest form
5.2 – Addition & Subtraction of Rational Expressions
Unlike denominators, LCM, simplification
This section focuses on adding and subtracting rational expressions with unlike denominators. You'll find the LCM, rewrite each fraction, and then combine numerators while simplifying the result.
Addition & subtraction
5.3 – Multiplication & Division of Rational Expressions
Product, quotient, simplification
This section covers multiplying and dividing rational expressions. You'll factor numerators and denominators, cancel common factors, and simplify the resulting expression.
Multiplication & division
5.4 – Equations Reducible to Quadratic Form
Exponential, reciprocal, and special types
This section teaches you how to solve equations that are not quadratic but can be reduced to quadratic form using substitution. Types covered include exponential equations, reciprocal equations, and equations of the form \((x+a)(x+b)(x+c)(x+d)=k\).
Exponential & reciprocal equations
5.5 – Real-World Problems
Work, rates, time, and distance applications
This section applies algebraic fractions to solve real-world problems involving work rates, shared tasks, time, and distance. You'll set up rational equations and solve them using the methods from previous sections.
