Continuation ... The height of the prism is x+1 units. Which expression in units could represent the length of this prism?

A   x-2 because V(2)=0

B  x-3 because V(-3)=0

C  x+2 because V(-2)=4

D   x-6 because V(0)=-6

Can i get clarification?

the length of the prism should be a factor of the given equation, so we see that for x= 2, the equation yields 0, so (x-2) is a factor of the equation. and hence it can be said that it can represent the length of the prism.
