  1. Solving Linear Inequalities
    Solve:
    1. 3x−10 3x-10 > 11 11
    2. 5−2x≤13 5-2x \leq 13
  2. Solving Quadratic Inequalities
    Solve each inequality
    i)
    graphically
    ii)
    algebraically using test intervals.
    1. 2x2−x−15≥0 2x^2-x-15 \geq 0
    2. −5x2−10x+40 -5x^2-10x+40 > 00
  3. Solving Higher Degree Polynomial Inequalities:
    Solve:
    1. 23(x+5)(x−4)3(x−3)8(x+2)11≥0 23(x+5)(x-4)^3(x-3)^8(x+2)^{11} \geq 0
    2. 23(x+5)(x−4)3(x−3)8(x+2)11 23(x+5)(x-4)^3(x-3)^8(x+2)^{11} < 00
  4. Factor First, then Solve Inequalities
    Solve: −2x4+3x3+18x2−17x−30≤0-2x^4+3x^3+18x^2-17x-30 \leq0
