1. Quick Crisp Review Imaginary and complex zeros come in pairs. Use the conjugate. Use the quadratic formula to identify zeros or x-intercepts. Substitute zero to determine the y- intercept. HW P 191 7,9,11,15,23,27 HW 1-5 Due Thursday

2. You will be able to divide polynomials. To use synthetic division: There must be a coefficient for every possible power of the variable. The divisor must have a leading coefficient of 1.

3. Divide using long division. Divide 2135 ÷ 6

4. Identify the intercepts y = 2x 2 -5x + 1

5. Write the quadratic equation that has a vertex of (3,1) and a point (4,-2) on the parabola.

6. Describe the end behavior of y = -6x 3 + 2x - 7

7. Write a polynomial function with zeros 0, -2, 5

8. Divide (2x 4 - 5x 2 - x + 1) ÷ (x + 2)

9. Determine the vertex of y = -x 2 – 2x - 4

10. Divide

11. Exit 1) What is the quadratic formula used for (in terms of graphing) 2) How do you find the y-intercept? 3) When should you use synthetic division and when should you use long division? 4) The toll for driving a segment of a certain freeway is $1.50 plus 25 cents for each mile traveled. Joy paid a $25.00 toll for driving a segment of the freeway. How many miles did she travel? A. 10B. 75C. 94D. 96E. 100
