- Grade 9 math module 2 solving quadratic equations. ±1. This method is used with the following properties as a guide: View Download Self Learning Module | RAR Published on 2022 August 3rd Description Contents: 1. A quadratic equation is a second-degree equation that has at ost two solutions. Mathematics 9: Quarter 1- Module 2: Solving Quadratic Equations by Extracting Square Roots. Jan 21, 2021 ยท In this module, you will learn how to solve quadratic equations by extracting square roots. Your mastery of the lessons is an important tool to solve many real-world problems related to quadratic equations. In this module, you will learn how to solve quadratic equations by extra WHAT I NEED TO KNOW PPREPREVIER! Solving quadratic equations by extracting roots is applicable if the equation is in the form ๐๐ฅ 2 + ๐ = 0 where ๐ and ๐ are real numbers and ๐ ≠ 0. A quadratic equation is a second-degree equation that has at most two solutions. 1. real number. square root B. constant D. sum C. Write the letter that you think is the best answer to each question on your answer sheet. It includes 3 methods for solving quadratic equations: (1) extracting the square root, (2) factoring, and (3) completing the square. Solve quadratic equations by: (a) factoring; (b) extracting square roots; (c) completing the square; and (d) using the quadratic formula. ±6 D. But, do not worry because there is one process that is applicable for all forms of quadratic equations that will be tackled in this module. SOLVING QUADRATIC EQUATION USING QUADRATIC FORMULA If you recall the previous lessons, the methods are just applicable for a specific quadratic equation. Quadratic Equations that can be written in the form x 2 = r, where r could be any real number, can be solved by the method called Extracting Square Roots. In this module, you will learn how to solve quadratic equations by extracting square roots. 3. Description Mathematics 9 (Quarter 1Module1Lesson 2) Objective 1. The document provides lesson materials on solving quadratic equations. SOLVING QUADRATIC EQUATION BY EXTRACTING SQUARE ROOTS quadratic or not. You were also given some applications to solve some real-life problems using this concept. In this module, you will learn different ways to illustrate WHAT I KNOW PPREPREVIER ! Find out how much you already know about solving quadratic equations by factoring. 2. What is the square root of 36? A. The last page introduces the (4) quadratic formula as the last method for finding the solutions or roots of quadratic equations. Answer all items. Get the equation of a quadratic in the form y = a(x – h)2 + k by substituting the obtained value of a and the x and y coordinates of the vertex in h and k respectively. 4. A. ILLUSTRATING QUADRATIC EQUATION In the previous year level, you have learned about linear equations and how to find their solutions. Every equation contains variables, the values of which need to be solved. After taking and checking this short test, take note of the items that you were not able to answer correctly and look for the right answer as you go through this module. If = 0 In the previous module, you have learned how to determine whether a given equation is quadratic or not. Mathematics 9: Quarter 1- Module 1:Illustrating Quadratic Equation. ±2 B. Develop speed and accuracy in solving quadratic equation. LEARNING COMPETENCY The learners will be able In the previous lessons, you learned about the different ways in solving quadratic equations, the concepts of the “nature of its roots” and the relationship of its roots and coefficients. A number which produces a specific quantity when multiplied by itself. . Examples are provided for each method. In this module, you will learn how to solve word problems that involves quadratic equations. Now, since you are in a new grade level, you will acquire knowledge and skills about quadratic equations. ±4 C. Mathematics 9: Quarter 1- Module 3: Solving Quadratic Equation By Factoring. Give the steps in solving quadratic equation using the four methods. For example, the process of “factoring” is appropriate only if the quadratic expression is factorable. Each time you complete a section of this program, you will be able to demonstrate the fundamental ideas of solving quadratic equations via (a) extracting square roots, (b) factoring, (c) square-rooting, and (d) applying the quadratic formula.
