Is my TI-89 calculator correctly expanding partial fractions?

Click For Summary
SUMMARY

The TI-89 calculator can correctly expand partial fractions when used properly. The user initially encountered an issue where the calculator returned a numerical value (.010075) instead of the expected algebraic expression. The solution involved clearing stored variables, specifically ensuring that 'x' was not assigned a numerical value. Once this was addressed, the calculator produced the correct expansion.

PREREQUISITES
  • Understanding of partial fraction decomposition
  • Familiarity with the TI-89 calculator functions

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 a lot.
