Yes sure, that's the part of the testing of immutable vs mutable. I'll check that.

Further I wonder about the other questions,

is it supposed to be,

Quadratic rotate(const double& a); or Quadratic& rotate(const double& a);

You won't return a reference but a new copy, so it would be : const Quadratic rotate(const double& a) const;

and if its fine if we use static 2x2 matrix for quadratic operations or we need a dynamic one?

I would keep it static, if there comes a need to make it dynamic then this should be a very easy change that's would be very easy to refactor.

Use  initialization lists where possible
