Using the completed chart below (image attached), we can write out the terms:
__________________________________________________
  y³ − 3y³ + 9y² + 3y² − 9y² + 27y ;

Then, we can combine the "like terms" ;
__________________________________________
y³ − 3y³  = -2y³ ;

+9y² + 3y² − 9y² =  + 3y² ;
___________________________________________________________
to get:  -2y³ + 3y² ;   and bring down the "+27y" ;
