  1. Quadratics Review

  2. 2 and -2 • At what point(s) does the graph of the polynomial q(x) = x² - 4 intersect the x axis?

  3. X = 6 • The area of a square can be represented by the expression 4x² - 4x + 1. if the area of the square is 121 square inches, what Is the value of x, in inches?

  4. B

  5. X = -4 • Write the equation for the axis of symmetry of the function f(x) = 4x² + 32x + 64?

  6. {-1, 1} • What is the solution set for the equation 3x² + 2x – 5 = 0?

  7. B • Which is the graph of y = x² - 4?

  8. D

  9. A

  10. 3 seconds • A ball is thrown in the air. The relationship between the time the ball is in the air in seconds (t) and the height of the ball in feet above the ground (h) is represented by h = -16t² + 46t + 6. How many seconds will it take for the ball to hit the ground?

  11. -2 or • What are the solutions to the equation 4x² + 7x – 2 = 0?

  12. 2.5 seconds • Jenny used the expression -16x² + 38x + 5 to determine the height of an object x seconds after it was hit into the air. How long does it take the object to hit the ground?

  13. C

  14. -4, 3 • What are the solutions to the equation x² + x – 12 = 0?

  15. -6, • What values are the solutions to the equation 2m² + 7m – 30 = 0?

  16. X = -3 or x = 1 • Solve 2x² + 4x – 6 = 0 for x.
