Consider Entropy change for van der waal gas

Prove that

ΔH = {bRT[1/(V_{2}-b)-1/(V_{1}-b)]}-2a/V_{2}+2a/V_{1}

2. Relevant equations

Ideal gas : PV = nRT ,

Enthalpy : ΔH = U + PV ,

Real gas : nRT = (P + a/(V^{2}))(V-b)

3. The attempt at a solution

I prove from PV = nRT in real gas it's going to be nRT = (P + a/(V^{2}))(V-b).

and Integral but it not come to ΔH = {bRT[1/(V_{2}-b)-1/(V_{1}-b)]}-2a/V_{2}+2a/V_{1}

I can't prove to this form. Can you help me to solute this problem?.

Thank you.
