Slide 1: Opening Assignment
State the solution: f(5) = 2x3 – x2 + 6x
Slide 2: Polynomial Practice
In pairs of two, find the answer to the problems on the practice form. Each person must answer a question in their own color. Work as an overall group to try to find the answers.

Slide 4: Polynomial Functions
Standard 2.6a-c:
Solve polynomial equations using various methods and tools which may include factoring and synthetic division. Sketch the graph of a polynomial function. Given the graph of a polynomial function, identify the x- and y-intercepts, relative maximums and relative minimums, using various methods and tools which may include a graphing calculator.
Slide 5: Polynomial Investigation 2
In your pairs, use your knowledge of like terms, distributive property and FOIL to add, subtract and multiply polynomials. Each person must answer a question in their own color. Double check each other’s work to ensure you have the right answer.
Slide 6: Polynomial Investigation 2
Students reveal their answers to the investigation.
Slide 7: ACT Tip
Questions sometimes test your knowledge of how properties operate. You need to know distributive, associate, etc.
Slide 8: Which of the following is an illustration of the distributive property?
A. B. C. D. E.
(12 • 25)(4) = 12(25 • 4) 7n + 2 – 3n = 7n – 3n + 2 (17)(b2)(5) = (17)(5)(b) 2 ab + ac = ba + ca x(x + 2) = x2 + 2x
Slide 9: Home Practice
Complete any problems in section 1 or 2 in chapter 6 (page 326 & 333) or (x4y7)-3 (10x3y5)-3 f(-1)=2x4 + x3 – 3x2 + 5x
