Lennard-Jones Potentials

The Lennard-Jones potential for the interaction of two molecules separated by distance R is
U(R)= A/R^12 - B/R^6

where A and B are constants. the equilibrium separation Re is that value of R at which u(R) is a minimum and the binding energy is De = -U(Re). Express:
(a) A and B in terms of Re and De.
(b) U(R) in terms of R, Re and De.
