Depends on what you mean with 2.

Abigail has a nice substitution trick, which strips out all
of the balanced text, and then if you have any parens left
it was unbalanced.  Small problems.  On long text with
deeply nested parens it is O(n*n) performance.  If you want
to nest with 2 types of balanced delimiters, good luck.  If
you want to report anything about where the problem was,
oops.  That text is gone.

By contrast scan the string once, pushing and popping from a
stack and this is trivial to solve.  It is O(n) runtime.
Extending to an arbitrary number of nested delimiters is
trivial.  And you don't throw away text.

This is a ridiculously simple parsing problem.  It is not
suited to RE engines.  Use the right tool for the job..

Cheers,
Ben
