2.4 Solve Polynomial Inequalities Algebraically

Interval Notation Bounded a a b b a b a b Unbounded a a b b

Solve and graph on a number line. -1

Example 1: Solve x3 – 3x2 > 10x algebraically Step 1: Rewrite as an equation, and put in standard form. Step 2: Solve for x (we can factor)

Example 2 Cont’d: (5, ∞) (-2, 0) Plotting our found x-values will help us find our intervals. This breaks our number line into 4 intervals. Test an x-value in each interval to see if it satisfies the inequality (5, ∞) (-2, 0)
