Calculators Is my TI-89 calculator correctly expanding partial fractions?

AI Thread Summary
When using the TI-89 calculator to expand the expression (3200x+16)/(x+400)^2 with partial fractions, users may encounter a numerical result like 0.010075 if the variable x is previously defined as a constant. To resolve this issue, it's essential to clear any stored values for x before performing the expansion. Once the variable is cleared, the calculator will correctly execute the partial fraction expansion.

I am trying to use partial fractions to expand (3200x+16)/(x+400)^2 on the ti-89 calculator but I keep getting .010075 as the answer when I use the expand function! What am I doing wrong here?

Clear the variables; if you have stored x as a constant (given it a value) then you will get a numerical result.
 
Ok this is embarrassing but it worked! Thanks alot.

Thread 'Urgent: Physically repair - or bypass - power button on Asus laptop'

Asus Vivobook S14 flip. The power button is wrecked. Unable to turn it on AT ALL. We can get into how and why it got wrecked later, but suffice to say a kitchen knife was involved: These buttons do want to NOT come off, not like other lappies, where they can snap in and out. And they sure don't go back on. So, in the absence of a longer-term solution that might involve a replacement, is there any way I can activate the power button, like with a paperclip or wire or something? It looks...
