1. QUADRATIC EQUATION

2. QUADRATIC EQUATION A Quadratic Equation in one variable is a mathematical sentence of degree 2 that can be written in the following standard form , + bx+c =0 where a , b , and c are real numbers and a≠0.  

3. ANOTHER KIND OF EQUATION! 1. 2. c = 12n - 5 3. 5.  

4. ANOTHER KIND OF EQUATION! 1. 2. c = 12n - 5 3. 5.  

5. ANOTHER KIND OF EQUATION! 8. 9 - 4x = 15 9. 10. h+6=0 11. 12.  

6. ANOTHER KIND OF EQUATION! 8. 9 - 4x = 15 9. 10. h+6=0 11. 12.  

7. Activity 1. QUADRATIC OR NOT QUADRATIC 8. (h-6)=0 9. =0 10. (w-8)(w+5)=14   2.   Identify which of the following equations are QUADRATIC and which are NOT

8. QUADRATIC EQUATION In a Quadratic Equation is the quadratic term bx is the linear term c is the constant term  

9.   a = 2 b = -5 c = -3 linear term quadratic term constant term  

10. Lets try this!           5. -7  

11. Lets try this!   11.   12. (2x+5)(x-1)=-6     14  

12. 1. + 9x +1 =0 2. 5 - 2 = 6x 3. 3x - = 7 4. - 4x =0 5. 2x(x-3) = 15   Try This Out! ACTIVITY 2 : Write each of the following in Standard Form, then identify the values of a, b and c. 6. (x+7)(x-7) = -3x 7. =0 8. - 5 = 0 9. ( = 10 . 2x(x + 4) =(x-3)  

13. Tell wether or not each of the following situations illustrates quadratic equations. 1. The length of the swimming pool is 8m longer than its width and the area is 105 .  

14. Tell wether or not each of the following situations illustrates quadratic equations. 2. A realty developer sells residential lots for Php4,000 per square meter plus a processing fee of Php 25,000. One of the lots the realty developer is selling Php625,000.
