SUMMER MATH WORK FOR STUDENTS ENTERING ALGEBRA 2, ADV. ALGEBRA 2 or ALGEBRA/TRIGONOMETRY The attached Math packet is assigned to you based on your registration for Algebra 2, Adv. Algebra 2 or Algebra/Trigonometry for the upcoming school year. Your assignment is to complete all of the problems in the packet (showing your work) and bring the completed packet to your Math class on the first day of classes. The packet will be checked for completeness at this time and you will receive a homework grade equivalent to three regular homework assignments. Over the first two days of classes, you will have an opportunity to ask questions and will review the assigned summer work. During the following week you will be given a test on this material. Directions: --Students need to work in pencil and show their work in the packet or on lined paper to accompany the packet. Round answers to the nearest tenth. --A calculator may be used on any of the problems in this packet and a graphing calculator is required for some.

Simplifying Polynomial Expressions Combining Like Terms - You can add or subtract terms that are considered "like", or terms that have the same variable(s) with the same exponent(s). Ex. 1: 5x - 7y + 10x + 3y 5x - 7y + 10x + 3y 15x - 4y Ex. 2: -8h2 + 10h3 - 12h2 - 15h3 -8h2 + 10h3 - 12h2 - 15h3 -20h2 - 5h3 Applying the Distributive Property - Every term inside the parentheses is multiplied by the term outside of the parentheses. Ex. 1: 3(9x4) 39x 34 27x 12 Ex. 2 : 4x2 (5x3 6x) 4x2 5x3 4x2 6x 20x5 24x3 Combining Like Terms AND the Distributive Property (Problems with a Mix!) - Sometimes problems will require you to distribute AND combine like terms!! Ex.1: 3(4x 2) 13x 34x 32 13x 12x 6 13x 25x 6 Ex. 2 : 3(12x 5) 9(7 10x) 312x 35 9(7) 9(10x) 36x 1563 90x 54x 48 Solving quadratic functions by factoring or quadratic formula Find the roots of each by factoring. 1. x2 -7x – 8 = 0 2. x2 – 5x + 6 = 0 3. x2 = 144 4. x2 -21x = 0 5. 4x2 -16x + 16 = 0 6. 2x2 +8x + 6 = 0 7. x2 + 14x = 32 8. 9x2 + 6x + 1 = 0 Find the zeros of each function by using the quadratic formula. 1. x2 – 3x – 8 = 0 2. (x – 5)2 + 12 = 0 3. 2x2 – 10x +18 = 0 4. x2 + 3x + 3 = 0 5. x2 – 5x + 10 = 0 Properties of Quadratic Functions in Standard Form For each function, a) determine whether the graph opens upward or downward, b) find the axis of symmetry, c) find the vertex, d)find the y-intercept. 1. f(x) = x2 – 4x + 3 2. g(x) = x2 + 2x + 3 3. f(x) = x2 – 3x 4. f(x) = x2 – 2x + 4 1 2 Find the minimum or maximum value of each function. 1. x2 + 2x + 6 2. -2x2 – 8x + 10 Right Triangle Trigonometry B 6.)
