(x+2)(−3x^2+3x+1)     {  we can line this up just like regular addition as follows  }

 

    x (−3x^2+3x+1)     =       -3x^3  + 3x^2  +  x

 

+  2 (−3x^2+3x+1)      =                 -6x^2    + 6x   +  2

_______________             ____________________

                                

                                            3x^3 - 3x^2  +  7x   +  2
