How do i solve for x on my ti-89?

How do i solve a problem like 3/x-2+21/x^2-4=14/x+2 and solve it for x?  I cant figure this thing out.  I also can't figure out how to show something is an inverse or find the formula of an inverse.

    But does not work

solve(3/x-2+21/x^2-4=14/x+2,x)

Second, for inverse, do this (note the "y=" part)

solve(y=3x^2 -2x+1,x)

The calculator will rewrite the formula as x = ...

Ti-84 Plus help!!


It seems like you're just starting off. And....

....The best thing you can do is begin hacking away at different buttons until you figure out what certain things do. I guarantee, that you will discover some pretty amazing things within the TI-84.

Compared to other calculators, the TI-84 is pretty user-friendly. Don't be scared.

In my opinion, Texas Instruments' customer service is one of the best in the nation. Call them for specific questions, they're great at the basics but not-so hot at the advanced. Friendly & helpful people, though.

Depends on what the black screen is caused by. If you review others on this site some have come up with a methods of keep hitting the 2nd key and left arrow key repeatly w/ success. Just depends. Some had problems because of 3rd party downloads and had to reset and reinstall to clear things up. Some had to connect to the computer and use ti connect device explorer to delete and reinstall even the os software. I guess it just depends on how far you make it to solving the problem. I had them that I couldn't fix or figure out.
