I get {x=-2,x=2}When we put in SOLVE MENU the equation x^2-4 = 0 , the result should be x= -2 and x=2 , but in result oly appears x=2 , WHY
??

What do you mean by "solve menu"? Do you mean the NumSolve application? If so, the NumSolve application solves numerically, not symbolically. You won't get all roots. There is't even a guarantee you'll get an exact solution.In Main Menu i appers {x=-2, x=2} !!
But why don't appers the same in the solve menu ?
