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

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

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.

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

Round 1 – Correct Response x² - x - 42

Round 1 – Correct Response

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

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

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

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

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

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

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

Round 4 Solve using the quadratic formula (answer in square root form): Player 4 is in the Hot Seat.

Round 4 – Correct Response
