Step-by-step explanation:
First cube both sides. Then, open the identity and cube - 4. As we have to cube so, - 4*-4*-4=-64. Now take x+y as common. We know that (x+y) =-4. So replace (x+y) to - 4. So it would be - 12xy. Now take - 64 to other side and it would be +64. So, it is solved.
PLEASE GIVE ME A THANK YOU
