TI-89 Factoring Not Working

I am trying to use the Factor function and it is not working. When entering f2, 2 for factor(, (x-5)^2,x) I should get x^2-10x+25, instead I get the result (5,)^2.... Why? There must be something in the mode that is set wrong, but I am not sure what..Your thoughts...

I think what you want to do is not to factor but to expand, which is the option right under factor [F2, 3]. expand((x-5)^2) = x^2-10x+25

Im trying to use to use the factoring feature and it keeps coming up as error: non-algebraic variable in expression. What can I do to fix this so it will factor out the problem for me?

You probably stored something to the variable you are using in the expression. Go to 'Catalog', press 'D', find 'DelVar', and press enter to put it on the input bar. Then type the variable you are using after it and press enter to execute the command. Then try your factoring problem again. Or, just use a different variable.

Does a TI 89 have an advantage over a TI 84 in a 10th grade algebra class? My sons teacher won't let him use an 89. He says it does too much of the work for him. Is this right?

the 89 is in my opinion not need/ approriate for a 10th grade algebra class, or worth the extra money.

for example the 84 wont output variables it must output a number

so your son may be doing factoring, if he inserts (x^2+2x+1) the 89 will allow him to enter it and factor it as (x+1)(x+1) or (x+1)^2 the 84 will not.

the 84 will do pleanty as far as graphing, finding zeros,plotting, calculations, and should get him any answer that he seeks so long that he knows how to use the 84. It just wont give him the intermediate steps the the 89 is able to give.

hope this helps

you are an idiot you are entering in the equation which you wish to be factored in the wrong order quit taking stupid pills and look it up in the manual do not annoy people with such an ignorant problem ask a friend. And if you don't have one then throw your calculator against the wall as hard as you can and learn to factor the old fashion way you ******

Factoring and expanding

try going to var link and deleting any variables like x and whatever you're trying to factor as they may be stored as lists and thus come out factored like that

When factoring or finding deriv. it gives me number?

oh yeah, you must've archived x, that is, you put a number onto the x variable so that the calculator calculates the answer for you, and THEN AUTOMATICALLY calculates the answer when x is in terms of that number. I am guessing you accidentally did 10[sto] x at one point. You can simply unarchived the x number and everything will be dandy!
