Summit Math Algebra 2 Book 4: Rational Equations and Expressions (Algebra 2 Series - 2nd Edition)

This textbook series supports both independent study and classroom learning, empowering students to learn at their own pace, whether working individually or collaboratively. The author makes each concept easy to understand and actively engages students in a step-by-step process of building genuine understanding, rather than memorizing formulas without knowing why they work. With careful pacing, clear explanations, and a detailed answer key for timely feedback and helpful guidance, the uniquely scaffolded approach allows students to learn math anywhere, at school or at home.

Written by a teacher with over 20 years of experience, each feature is designed to benefit students. Published as separate books instead of a single textbook, students feel a sense of achievement when they finish each book, making learning feel less intimidating. Each lightweight book has 2 parts. The first half uses small steps to guide students through the process of constructing each concept, while the second half provides additional practice to reinforce learning and improve retention. Every section includes an answer key to provide teacher-like feedback that helps students keep moving forward. This curriculum is named Summit Math to reflect the author's belief that learning is like hiking. Anyone can reach the summit, at their own pace, if they keep taking small steps.

Book description:
In this book, you will learn how to manipulate a rational expression by multiplying it by a disguised form of 1. You will use this skill to do the following operations with rational expressions: addition, subtraction, multiplication and division. You will then learn how to solve rational equations by identifying common denominators and eliminating the fractions. Near the end of the book, you will learn that some equations have extraneous solutions. This book builds on Algebra 1: Book 5 and Algebra 2: Book 3.
