When factoring or finding deriv. it gives me number?
Before it works fine, when I try to factor, expand, find d but now it give me only numbers. I'm guessing I probably messed up on some settings and I try going through the mode menu changing everything and nothing worked.

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!

The polynomial cannot be factored in the set of Real numbers: The roots of the polynomial equation are complex.
You should use the command cFactor( found under F2:Algebra> A:Complex>2:cFactor(
However, you should set the Mode Complex>Rectangular, and the EXACT/APPROXIMATE mode to Exact, otherwise your roots will be in decimal representation.
Simple. The calculator interpreted what you entered as much as it could. However when it got to the 2mn part, it recognized the factor 2 and carried out the multiplication of 3 and 2 to give 6, but you never defined for it what mn was. To make sure it understands, insert an explicit multiplication sign between m and n, otherwise it considers the grouping as some new variable. Implicit multiplication cases are easily recognized when they involve a number and a variable, but not when two letters follow one another.
Note: I believe you are not using the right command. Yes, it gives the result here, but the command you should be using is factor( rather than expand(. expand( will open up parentheses and lengthen the expressions. Just thought you might want to know.
I am somewhat puzzled at your affirmation concerning factoring and expanding algebraic expressions. The TINspire does not do symbolic algebra, only the TI NspireCAS does. If you have the TINspireCAS, (version 2.x) you can
press the HOME button, then select A:Calculate.
In one of the pages, press MENU.
Use Down Arrow or enter the number 2:Factor, or 3:expand
In the command line, expand( , complete the command by entering the expression, close the right parenthesis and press [ENTER].
The calculator should give you the expanded result.
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
There must be something that has been introduced to your area that is causing distortion in your WiFi signal. 802.11 or WiFi is very susceptible to noise or signal distortion and can come from many things from interfering objects to other wireless signals such as Wireless phones. There are also many other things that can cause signal distortion I would look to see if you have added anything new around the time the unit lost signal. If your unit is working properly when you are closer to the router than this has to be the problem. Range is a big iffy factor when messing with WiFi.
