Lesson for Illustration of Quadratic Equations

2. OBJECTIVES:
•DESCRIBE THE STANDARD FORM OF A QUADRATIC EQUATION AND
IDENTIFY THE VALUES OF A,B ,AND C IN THE QUADRATIC
EQUATION.
•ILLUSTRATES QUADRATIC EQUATIONS IN STANDARD FORM.
•APPRECIATE THE IMPORTANCE OF QUADRATIC EQUATIONS IN OUR
DAY TO DAY ACTIVITIES

3. WHICH OF THE FOLLOWING EQUATIONS ARE
QUADRATIC EQUATIONS

4. DOES IT ILLUSTRATE ME?

5. DID YOU FIND THE ACTIVITY CHALLENGING? WERE
YOU ABLE TO REPRESENT EACH SITUATION BY
MATHEMATICAL STATEMENT? FOR SURE YOU WERE
ABLE TO IDENTIFY THE SITUATIONS THAT CAN BE
REPRESENTED BY QUADRATIC EQUATIONS. IN THE
NEXT ACTIVITY YOU WILL WRITEQUADRATIC
EQUATIONS IN STANDARD FORM.

7. QUIZ
DIRECTIONS: TELL WHETHER OR NOT EACH OF THE FOLLOWING SITUATION ILLUSTRATES QUADRATIC
EQUATIONS. JUSTIFY YOUR ANSWER BY REPRESENTING EACH SITUATION BY A MATHEMATICAL
SENTENCE.
1.THE SQUARE OF A NUMBER IS ADDED TO TWO TIMES THE NUMBER AND THE SUM IS 24.
2.THE WIDTH OF A RECTANGLE CARD IS 2CM LESS THAN THE LENGTH AND THE AREA IS 35CM2
3. A FLOWERBED IS TO BE 3M LONGER THAN ITS WIDTH. THE FLOWERBED WILL HAVE AN AREA OF 70M2
4. ANGELA IS 4 YEARS YOUNGER THAN GENESIS. FOUR YEARS LATER, GENESIS WILL BE TWICE AS OLD AS
ANGELA.
5.A RECTANGULAR BAHAY-KUBO WITH THE DIMENSION OF 11M MORE THAN ITS WIDTH BUILT IN A
RECTANGULAR BACKYARD. THE AREA OF THE BAHAY-KUBO IS 85M2

8. PERFORMANCE TASK: SUBMIT YOUR OUTPUT TOMORROW.

9. FOR ANY ENDEAVOR WE TRY TO ACCOMPLISH,
WE CONSIDER LIMITATIONS OR
RESTRICTIONS TO DIFFERENTIATE ONE THING
FROM ANOTHER.
DO YOU OBSERVE THE DO'S AND DON’TS
WHENEVER YOU GO OR WHENEVER YOU TRY TO
ATTAIN AN OBJECTIVES?
