i make this program to compute the value of integral ,, but at some example i cant get result .. like this example ,,can you help me to know the problem

syms x; syms E;

 syms c;
 syms b;
 syms m;
syms g(x);
 g(x)=sqrt(2*m*(E- (1./(c-(b./(x.^2))))))
G(x)=int(g(x),x)

pretty(G(x)) G(x)-G(1) pretty(G(x)-G(1))
