25. V = 2x^3 - 11x^2 + 10x + 8
V = l x w x h
V= (2x + 1) (x-4) (?)

V= (2x^2 - 7x -4)(?)

Plug in volume 

2x^3 - 11x^2 + 10x + 8 = (2x^2 - 7x - 4)(?)

Divide to find your unknown

2x^3 - 11x^2 + 10x + 8/ 2x^2 - 7x -4 = ?

? = x -2 

then we can multiply our dimensions to double check! 

(x-2)(x-4)(2x + 1) = 2x^3 - 11x^2 + 10x + 8

Which works out when you distribute so it works!
