Section 1.7 Slide 2 Linear Inequalities Isolate x. Write your answer in interval notation. Slide 3 Two Types of Nonlinear
Inequalities Polynomial Rational Slide 4 Polynomial Inequalities Make sure you have 0 on one side. Factor the nonzero side and find the zeros. Mark the zeros on a number line. Test each interval of the number line between the
zeros you marked.
zeros Choose the intervals that satisfy your inequality. Slide 5 Rational Inequalities Add or subtract to get 0 on one side. Do NOT multiply
both sides times the denominator!
both Add or subtract the fractions to obtain a single fraction. Factor both the numerator and denominator and find the
zeros of both.
zeros Mark all zeros on a number line and test the intervals. Choose the intervals that satisfy your inequality. Make
sure you do not include any numbers that give you a 0 in
the denominator for your answer.
