Answer: "
-2y³ + 3y²<span>
+ 27y " .
_______________________________________________________Refer to the completed chart below (image attached).</span>
_______________________________________________________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" ;
___________________________________________________________ Answer: "
