Simplify the rational expression. State any restrictions on the variable. 


A. t + 4; t ≠ 8 B. - t + 4; t ≠ - 8 C. t - 4; t ≠ - 8 D. - t - 4; t ≠ 8
 I think it would be C. 
t^2 -4t -32 = (t+4)(t-8)

so

t^2 -4t -32
------------- 
      t-8

= (t+4)(t-8)
--------------
     t-8

= t+4

answer is A. t + 4; t ≠ 8
