x^2 + x  - 12    factors  as   (x + 4) ( x - 3)

 

3x^2 + 11x  - 4 factors as  ( 3x - 1) (x + 4)

 

x^2 - 4  =  (x + 2) (x - 2)

 

So we have

 

 

   (x + 4) ( x - 3)

  ___________

     (x - 2)

_______________         =

   (3x - 1) ( x + 4)

  ____________

   (x + 2) ( x - 2)   

 

 

(x + 4) ( x - 3)           (x + 2) ( x - 2)

____________    *   ____________       =

      (x - 2)                 (3x - 1) (  x + 4)

 

 

(x + 4) ( x - 3) ( x + 2) ( x - 2)

______________________    =

   (x - 2) ( 3x - 1) ( x + 4)

 

 

(x - 3) ( x + 2)

___________     =

     3x - 1

 

 

x^2 - x - 6

________

    3x - 1
