What version do you run? If you look in the on-calculator "Catlg" for the functions and press help, both cFactor and cSolve are included.

Code:


Syntax: 
cFactor(Expr) 
Returns an expression factorized over the complex field (on Gaussian integers if there are more than two). 
Example: 
cFactor(x2*y+y) ➔ (x+i)*(x-i)*y 
cFactor(x2*y2+y2+2*x2+2)

Syntax: 
cSolve(Expr,Var) 
Returns the solutions, including complex solutions, of Expr, for Var. If Expr is an expression, solves the equation Expr=0. 

Example: 
cSolve(x^4=1,x) ➔ {-1, i,1, −i } 
cSolve(u*v-u=v and v2=u,[u,v]) ➔ {[0.,0.],[2.61803,1.61803],[0.38196,−0.618033]}

Hope this helps,

Cheers, Terje
