I'm not sure how i can show work for this problem:
\(\lim_{x\to -6} \frac{-12}{(6+x)^2}\)

Note that as  x →  -6  from both sides   (6 + x)^2  takes on a very small value  [ ≈ 0 ]

 

So   

 

lim                      -12                   -12

x → - 6           ________   =      ____  =      -∞      [ i.e., the limit does not exist ]

                       (6 + x)^2              ≈ 0
