Today’s Objectives:

1. Today’s Objectives: • To review the following topics for the Ch. 8 Test: • Factoring Quadratics • Graphing a Parabola • Solving Quadratics by Factoring • Solving Quadratics by Using the Quadratic Formula

2. Before We Begin . . . . • Choose an appropriate team name. • Assign each player a number, 1 through 4. • Make sure each player has paper and pencil.

3. Rules of the Game. . . . • You may only speak to players on your own team. • The player in the hot seat is not allowed to speak to anyone. • All parts of your answer must be correct & labeled with the correct units in order to receive points. • A correct answer from the hot seat player is worth 2 points; a correct answer from the team is worth 1 points. • Make sure that the answer you submit includes your team name and player number.

4. Round 1 Player 1 is in the Hot Seat. The team works on the problem and one paper from the team will be selected. • Factor the Quadratic using a generic rectangle x² - x - 42

5. Round 1 – Correct Responsex² - x - 42

6. Round 1 – Correct Responsex ² - x - 42

7. Round 1 – Correct Response (x + 6)(x - 7)

8. Round 2 • Player 2 is in the hot seat. Remember one paper from the team will be collected. • Show how would you find the x-intercepts of the parabola y = x² + 6x + 8. • Find the y-intercept.

9. Round 2 – Correct Response • To find the x-intercepts, first factor using a generic rectangle.

10. Round 2 – Correct Response • When finding the x-intercepts, let y = 0.

11. Round 2 – Correct Response • To find the y-intercept, let x = 0.

12. Round 3 • Player 3 is in the Hot Seat. • Solve the following using the Zero Product Property. • 2x² - 7x – 15 = 0

13. Round 3 – Correct Response • First factor using a generic rectangle.

14. Round 2 – Correct Response • Then set each factor equal to zero and solve.

15. Round 4 Player 4 is in the Hot Seat. • Solve using the quadratic formula (answer in square root form): 3x² + 5x + 1 = 0

16. Round 4 – Correct Response

17. Round 4 – Correct Response
