  1. Quadratic Formula: gives the solution of in terms of the coefficients a, b & c. The solutions of the quadratic equation are

  2. 1st 2nd Ex: 1 Solve x2+ 9x +14 = 0 a = b = c =

  3. 1st 2nd Ex: Solve x2- 6x +10 = 0 a =1 b =-6 c =10

  4. We must solve to get x2 by itself 1st! add 48 divide by 3 take the square root of both sides

  5. Solve: 6x2 – 11x + 3=0 (2x – 3) (3x – 1) = 0 x = 3/2 x = 1/3

  6. Write the following quadratic in factored form: 6x2 – 11x + 3 (2x – 3) (3x – 1)

  7. Find the x-intercepts for: y=6x2 – 11x + 3

  8. Find the roots for: y=6x2 – 11x + 3

  9. For the following quadratic, state the nature of the roots: y=6x2 – 11x + 3 a. 2 real solutions b. 1 complex solution c. 1 real solution d. 2 complex solutions

  10. Solve 1) x2 + 5x + 6 = 0 2) x2 + 7x + 6 = 0 3) 6x2 + 15x = 0

  11. Find the zeroes of the function. x = 1/3, -2

  12. Famous cliff diver Robbie Jarvis dives off of a 138 foot cliff. After t seconds, his height h (in feet) is modeled by: h = -16t2 + 138 How many seconds does it take him to reach the water? Bonus: Will there be a splash? t = 2.94 seconds
