Answer:

2x^3 +9x^2 y+9xy^2 +3y^3

Step-by-step explanation:

STEP

1

Equation at the end of step 1

3 • (x - y)3 - x3

STEP

2

2.1 Evaluate : (x-y)3 = x3-3x2y+3xy2-y3

Checking for a perfect cube :

2.2 2x3-9x2y+9xy2-3y3 is not a perfect cube

Final result :

2x^3 + 9x^2 y+ 9xy^2 + 3y^3

(I hope this helps you)
