Ill give medals and become a fan :)))!

rectangular blocks of limetstone are to be cut up and used to build the front entrance of a new hotel. The volume V, in cubic metres of each block can be modelled by the function
V(x) = 2x^3+7x^2+2x-3

a) Determine the dimensions of the blocks in terms of x

Okay so i tried this question and I thought i was supposed to synthetically divide so I got (2x+6)(x+1)(x-0.5) = v(x)

however the back of the book tells me the answer is (x-3)(x-2)(x+1)

Where did I go wrong? Was I not supposed to synthetically divide?
