Comment(by elazutkin):

 Try not to overdo it: one can always complain that it doesn't work for
 negative and complex numbers, quaternions, and octonions too --- there are
 generalizations for these and other cases. ;-)

 It reminds me of my robotics prof, who asked us to write a solver for a
 trivial quadratic polynomial, and embarrassed students by pointing out
 that their solution doesn't work for complex numbers, doesn't show that
 there are no solutions ({{{a == 0, b == 0, c != 0}}}), doesn't detect
 degenerated linear cases ({{{a == 0, b != 0}}}, or {{{a != 0, b == 0}}}),
 and in some cases any values are valid solutions ({{{a == 0, b == 0, c ==
 0}}}).
