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