you need divide the volum equation by x-2 and will get the right answer 
- can you calcule it ?

jhonyy9 · Answer

- so if you check the last term of volum equation is -24 and the last term of height equation is -2 so from this what will result for answer what you need multiplie by -2 to can getting -24 ?
