How do I find the divisor pair list on the Ti-84 plus? For example, 20 would be 1,20 or 4,5. I did this before using the y= function. y1 and y2 show the divisors on the table and x=20. It also involves using the the table set up and some other button. Thank you for helping me. :0)

I have had the same problem luckily i figured out what to do. 1. press the apps button 2. then there should be an unwanted app(it was the only one on mine) 3. pick it and hit enter 4. go to uninstall on the top of ur screen problem solved!!!! hope this helped

This is my first post on this site, but I've had friends at school ask me about this. Apparently I'm like a calculator genius or something...
One solution I know of is clearing the RAM. Sounds strange, doesn't it? But it fixed three different calcs.
Be sure to back up or archive important data before doing this.

I am afraid you cannot use the TI8xPlus family of calculators to solve linear systems in matrix form. In this calculator, matrices must have real coefficients.
You can however separate (expand) the problem into a linear system of 4 equations in 4 unknowns and try to solve it with the calculator.
Similarly, you rewrite the second complex equation substituting a+ib for X and c+id for Y, then expand the binomial products, gather the real parts on the left together, and the imaginary parts on the left together. After that you equate the real part on the left to the real part on the right, and do the same for the imaginary parts.
If I did not make mistakes during the expansions and the gathering of terms you should get the following equation
-(8a+8c+10d) +i*(-8b+10c-8d) =0+i*0 from which you extract an equation for the real parts, -(8a+8c+10d)=0 and another for the imaginagy parts i*(-8b+10c-8d) =i*0
If I did not make mistakes (you should be able to find them, if any) your system of two linear equations with complex coefficents has been converted to a system of 4 linear equations with real coefficients.
8a-15b-8c=10
15a+8b-8d=0
8a+8c+10d=0
-8b+10c-8d =0
Now, you can in theory solve this system with help of the calculator, to find a, b, c, and d. When these are found, you can reconstruct the X and Y solutions.
Now get to work: Ascertain that my extracted equations are correct, then solve for a, b,c, and d, and reconstruct X and Y.
I am no seer, but my hunch is that this system is degenarate. I will not explain what that means.

i would say use the normal key pad or send it in to T.I to fix.

what helped for me is leaving it w/h any battery's (no backup battery either) for a few days. Now miraculously it works!
