1. Section 6.4 Solving Polynomial Equations Obj: to solve polynomial equations

2. Solving by Graphing (only real solutions) Graph the related function and find its __________ or __________. Graph and Solve: x 3 + 3x 2 – x – 3 = 0 Solutions: _______________

3. Recall: Factoring a “Difference of Squares” a 2 – b 2 = (a + b)(a – b) Solving by Factoring a Sum or Difference of Cubes also has an algorithym:

5. Solve.

7. Factor by Using a Quadratic Form. Has the form of a quadratic, so factor it as one----- x 4 + 7x 2 + 6x 4 – 6x 2 - 27

8. Solve.
