1. HELLO 9-CECILIA PREPAREDY BY: CHRISTIAN RHEY NEBRE

2. REVIEW FIND THE ROOTS OF THE FOLLOWING NUMBERS 1.√49 2.√196 3.√25 4√4/25 5. √.36/ 25 7 13 5 2/5 6/5

3. ANALYSE THE GIVEN FIND THE FACTORS OF THE GIVEN EXPRESSION AND FND ITS SOLUTIONS = 0   1. Give the factors of 12 whose sum is 7?

4. OBJECTIVES 1.Recall the methods of extracting square roots 2. Solve quadratic equations by extracting square roots and factoring

5. EXAMPLES = 121 - 100 = 64 = 3 3 =   FIND THE SOLUTIONS/ROOTS OF THE FOLLOWING QUADRATIC EQUATIONS

6. APPLICATION FIND ITS SOLUTIONS AND ROOTS (BY PAIR) AND DISCUSS TO THE CLASS = 100 -12 = 24 = -22 = 0  

7. ASSESMENT FIND THE ROOTS OR SOLUTIONS OF THE FOLLOWING QUADRATIC EQUATIONS ( 2 POINTS EACH) -75 = 25 = 169 = -15 -200= 200 = 45-12X - 25  

8. GENERALIZATION 1.HOW MANY SOLUTIONS THAT A QUADRATIC EQUATION HAVE? 2. WHAT IS THE CHALLENGING EXAMPLE? 3. Let the students share their reflection as the appreciate the concept of finding roots of quadratic equation and what are the steps in finding the roots

9. THANK YOU CLASS HAVE A GREAT DAY
