why are people are making this so complicated. I suggest this.

eq:  'diff(x,t)^2+5*x^2=8;

solve(eq, 'diff(x,t));    /* solve for highest derivative.  There are 2 
solutions */

ode2  (part(%,1), x t);  /* pick one */

solve(%,x);  /* since the result from ode2 presents x in an implicit 
format */
