Solving polynomial equations
1) Factor first or use quadratic formula
2) A product is zero if at least one or more of its factors is zero, ab=0 a=0 or b=0 or both
Example: solve
a)    
   
    

Solving rational expressions
  iff p(x)=0 and q(x)0 therefore solve p(x)=0 but make sure that the answers do not make the
denominator equal zero.

  
    
    
   
Polynomial inequalities
1) Solve the corresponding equality
2) Construct a sign chart
3) Choose the appropriate intervals
