Normal form : normal

normal takes as argument an expression. The expression is considered as a rational fraction with respect to generalized identifiers (either true identifiers or transcendental functions replaced by a temporary identifiers) with coefficients in $ \mathbb {Q}$ or $ \mathbb {Q}$[i] or in an algebraic extension (e.g. $ \mathbb {Q}$[$ \sqrt{{2}}$]). normal returns the expanded irreducible representation of this rational fraction. See also ratnormal for pure rational fractions or simplify if the transcendental functions are not algebraically independant.
Input :
normal((x-1)*(x+1))
Output :
x^2-1
