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.
