Well in my humble opinion both the Mathematica and Matlab solutions you like are misleading: they give the real and complex solutions to x^2-x = plus-or-minus 3; but if complex solutions are allowed then there are many more than the pair which those systems give, since there are many more *complex* numbers whose modulus is 3 than +3 and -3.
So I (for one) would be unhappy if SAGE gave the same solutions as those two inferior systems! John Cremona -- Prof. J. E.
