I found a video comparision, I would like to consolidate Classpad II is the best solution also if 6 years old....


I read a comment: 


..i mean:Solve(a*x^3+b*x^2+c*x+d=0,x) My Ti nspire cx cas solves this cubric equation in 31.24 seconds.Yes its a long one.I have to scroll left and right for awhile.My ti 89 can not do it,though it still better in ways.Good luck!!!



That is not good for my idea the Classpad is the best one  :rolleyes:


I tried to solve ax^3+bx^2+cx+d=0,x but without success...


Does TI Nspire solve really?


What can we do to win the battle?






thanks for your feedback
