5.  Solve polynomial inequalities  Solve rational inequalities

6.  Rewrite the inequality so that zero is alone  Solve the inequality as if it were an equation  Use the boundary number (the solutions you just found) to separate possible solutions into intervals  Use test values or a graph to determine which intervals are greater or less than zero

7. x 3 +7x 2 +12x>0 intervalTest value + or -

8.  Write the inequality in the form of a ratio. p(x) q(x)  Solve for p(x)=0 and q(x)=0  The numbers are your boundary numbers  Discover which intervals are positive and negative
