2. Warm Up 12/1/14 1.Identify all the real roots of the equation: 3x 3 - 18x 2 – 9x + 132 2.Identify whether the degree is odd or even, whether the leading coefficient is positive or negative, describe the end behavior, and sketch the graph without using the calculator: 2x 3 + 3x 2 - 4x

3. Warm Up 12/2/14 3.Write the polynomial that has roots 3 and 5 + i. 4.Expand using Pascal’s triangle and the binomial theorem: (2x – 3) 4

4. Warm Up 12/3/14 5. Write the polynomial that has roots - 2 and √3. 6.Identify the roots of the equation. State the multiplicity of each root. x 3 + 5x 2 – 8x - 48

5. Warm Up 12/4/14 7. Write the polynomial that has roots - 2 and 5 + i. 8. If p(x) = 3x 3 - 18x 2 – 9x + 132 and q(x) = 2x 3 + 3x 2 - 4x, then what is p(x) – 3q(x)?

6. Warm Up 12/5/14 9. If the area of a rectangle is 6x 2 – 7x – 5 and the length is 3x – 5, write an expression that represents the width. (Hint: do long division!) 10. If a(x) = 2x 3 + 18x 2 – 9x + 42 and b(x) = 6x 3 + 7x 2 - x, then what is a(x) – 4b(x)?
