Classwork - Chapter 6 #1-2: Find the greatest common factor: 1) 8a2b3, 10ab 2) 35x3y2, 10x*y, 5x5y3 #3-10: Factor the expression completely. (If it cannot be factored write prime.) 3) 423 + 32 4) 3x2 + 6x - 105 5) x4 - 81 6) x2+9 7) (2y + 3)2 - 5(2y +3) +6 8) 20p q - 2p q - 4pq 9) 624 + 3023 - 15z2 - 75z 10) 48x5y2 - 243xy? #11-16: Find the solution set to each equation. 11) (x - 3)(x + 1) =0 12) 4x(2x - 3) = 0 13) 5x2 = 2x + 3 14) a2 + 12a + 36 = 0 15) -2463 + 27b = 1862 16) 2p3 + 5p2 - 8p - 20 = 0 17) Find the zeros of the function. What are the x-intercepts of the graph of the function? f(x) = x2 +9x +14 18) Suppose that f(x) = x2 + 5x + 3. Find the values of x such that f (x) = 17. 19) Find the domain of the function: f (x) = x2_4 20) The outside dimensions of a picture frame are 40 inches by 32 inches. The area of the picture within the frame is 1008 square inches. Find the width of the frame. (Remember to define your variable and give your answer in a complete sentence.
