use the substitution sqrt(x) = cost
use trigonometric formulae to simplify [1-cos t] and [ 1+ cos t], sint using the half angle formulae
cancel off the common factors
simplify then again use trigonometric formulae to change the square terms to first degree expressions before integrating.
again use trigonometric formulae to change the variable back to x
