autosimplify() Xcas cmd
Without the complete control of the flags (CAS settings) in the hp-prime, many algorithms fail, for this reason the following command is important

Please HPP-TEAM include in the next update, autosimplify() Xcas cmd

autosimplify(); // returns 0/1/2
autosimplify(0); // none
autosimplify(1); // regroup or medium
autosimplify(2); // simplify or maximum

PHP Code:
#cas
testBeta1():=
BEGIN
 purge
(x,y);
 print;
 print(
"autosimplify off");
 
autosimplify(0);
 
list0 := [ x^22*]; // Solving a system of two equations
 
print(""+list0);wait;
 
expr0 := subst(list0(2),list0(1)); // substitute y = x² in y = 2x + 3
 
print(""+expr0);wait;
 
expr0 := expr0-(2*3);  // substract 2x + 3 
 
print(""+expr0);wait;
 
expr0 := simplify(expr0); // simplify
 
print(""+expr0);wait;
 
expr0 := factor(expr0);
 print(
""+expr0);wait;
 
lsolx := [ part(left(expr0),1)=0part(left(expr0),2)=]; // zero factor theorem
 
wait;
 return 
lsolx;
END;
#end
