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

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

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
