Review Exercise 4 – Algebraic Factorization and Applications This review exercise is designed to consolidate the concepts of factorization, HCF, LCM, and polynomial roots covered in previous exercises. It includes both theoretical questions and practical applications. Question 1 tests conceptual understanding through multiple-choice questions, covering factorization, HCF, LCM, square roots of polynomials, and properties of cubic polynomials. Question 2 provides practice in factorizing various algebraic expressions. Question 3 focuses on finding the HCF and LCM using the prime factorization method. Question 4 reinforces methods for finding the square root of polynomials through both factorization and division techniques. Question 5 applies algebraic factorization to a real-life scenario, requiring students to interpret and solve a practical problem involving loan repayment. Students should carefully follow each method, show all working steps, and interpret their results accurately. This exercise is intended to strengthen problem-solving skills and ensure readiness for advanced algebraic problems.
