When the concentration o molecules inside a cell is different form the concentration of molecules outside a cell, we can either call it hypertonic or a hypotonic solution, and the difference between the two concentrations is called a concentration gradient.
Hypertonic - name given to a solution that has a bigger concentration than the concentration in a cell.
Hypotonic - name give nto a solution that has a smaller concentration than the concentration in a cell.

Explanation:
(X3+8)+( 2X2+ 4X)
(X+2)(X2-2X +4) + 2X(X+2)
(X+2)(X2-2X+4+2X)
(X+2)( X2+4)
