```In Maxima, using a decimal point in a number indicates you want to
calculate with floating-point (approximate) numbers, so the result will
often not be exact.

For exact calculations, use fractions, e.g.

3^(1/2)/(2-3^(1/2)) - (2*3^(1/2)+3)/(4-3)

or

sqrt(3)/(2-sqrt(3)) - (2*sqrt(3)+3)/(4-3)

Then you can use any one of Maxima's functions to reorganize/simplify the
expression.  In this case, ratsimp gives 0; in other cases, you may want to

-s
