Note that this is different than https://github.com/jiggzson/nerdamer/issues/565. In that case, simplify failed to do anything at all (though a simplification was easily possible.)
In this case it does do something, but what it does is incorrect. I can't tell yet from the code whether the underlying reason for these two issues is the same, but this one is clearly more serious.
The expression
simplify((-2 x -2 x^2 - 2)/(x + x^2 + 1))gives
2instead of the correct answer of-2.Note that this is different than https://github.com/jiggzson/nerdamer/issues/565.
