MATHEMATICS 8 QUARTER 1 Week 1 Competency The learner factors completely different types of polynomials (polynomials with common monomial factor, difference of two squares, sum and difference of two cubes, perfect square trinomial, and general trinomials). M8AL-Ia-b-1 Expectations This module was designed to help you factor polynomials. As you go over the activities, you will have mastery of the different types of factoring such as Greatest Common Monomial Factor, Difference of Two Squares, Sum and Difference of Two Cubes, Perfect Square Trinomial, Factoring by Grouping and other types of factoring. After going through this module, you are expected to: 1. Enumerate the different types of factoring; 2. Differentiate one type of factoring from another type; 3. Distinguish factorable expressions; and 4. Factor polynomials completely. Pre-Test Read and analyze each question carefully. Choose the letter of the correct answer. ____1. Which of the following are the factors of 21x2 + 7x? A. 2x(7+21x) B. 7(x+3) C. 7𝑥(3𝑥 + 1) D. 7𝑥(3𝑥 − 1) ____2. Let A: 16x2 – 81; B: (4x – 9)(4x + 9). If x = 4, which statement is true about the given expressions? A. A >B B. A B B. A
