2. Interval Notation Bracket – closed circle on a number line
include the number
Parenthesis – open circle on a number line
do not include the number

3. Polynomial Inequalities
Get zero on one side of the inequality
Put the inequality in standard form
Factor the inequality
Set each factor equal to zero
Solve the equation
Put all the answers on the number line
Plug in numbers to the factored inequality to see if it is positive or negative
Write positives and negatives on the number line

4. Polynomial Inequalities
Look at the factored inequality to see if you want positives or negatives
Write your answer in interval notation
Be careful of brackets and parenthesis
