Hello folks- I am trying to use my TI-89 Titanium to factor and do expanding work. Entering the correct information, I get a return of

ERROR: Argument Error

Why is the calculator not doing its job? I tried the F6 menu thing from another article on the internet and it did not help. Any help with this would be appreciated.

I reset the calculator and it did its job- though a solution would be handy.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

You have to download the next program for multivariable function limit from:

Use the rand() function. If you give it a positive integer argument *n*, it will return a random integer in the range in the interval [1, *n*]. You'll find rand() in the MATH/PROBABILITY menu.

In Home screen press [F2: Algebra] then select [3:expand(]. The command echoes on main command line. Complete the argument by typing in (x-0.3)(x/2 plus 0.15) and close the right parenthesis of the expand( )function.

You can also use the identity (special product) (a-b)(a plus b)=a^2-b^2. It is not that clear here, but if you you factored out the 1/2 you will see it.

1/2*(x-0.3)(x plus 2*0.15)=1/2*(x-0.3)(x plus 0.3)= 1/2*(x^2-0.3^2)

Having gone over a month with no response, I assume this is no longer a problem.

Hello,

Since this is a discrete distribution, you can only calculate it at integer values of the variable. Hence the last argument in the function (0.75) must be an integer. As you gave a decimal number where an integer is required, the calculator returns a domain error.

Hope it helps.

Using solve and factor requires correct mode and proper equation set up. Ref to manual might help.

An argument must be in a specified domain. For example, ans(100) is not valid because the argument for ans() must be in the range 1–99.

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

It might be nice to see a solution to this, but I reset the calculator and it seems like everything is working perfectly.

I have the same problem

Trying to do long division using the propFrac function and keep getting an argument error.
