  1. Section 5.8The Quadratic Formula Obj: to solve quadratic equations using the quadratic formula Obj: to use the discriminant to state the number and nature of solutions to a quadratic equation

  2. Y = a + bx + c Quadratic Formula: Discriminant: Tells you what type and how many solutions you can expect to get from your equation

  3. Discriminant: The discriminant tells you how many andwhat type (nature) of solutions to expect from your equation. • If is positive, then your equation will have 2 real solutions. • If = negative, then your equations will have 2 imaginary solutions. • If = 0, then your equation will have 1 real solution.

  4. Ex 1 3 - 5x -2 = 0

  5. Ex 2 3 - x = 4

  6. Ex 3 2 = -6x - 7

  7. Ex 4 -2 = 4x + 3

  8. Assign: Pg. 289 column 1 • Solve using the quadratic formula • Use the discriminant to predict the number and nature of the solutions.
