Log ( (x^2 - 4) / (x - 2)^2 )

Log ( ((x + 2)(x - 2)) / (x - 2)^2 )

Log ( (x + 2) / (x - 2) )

Log (x + 2) - Log (x - 2)
.

Expand or simplify?
Expanded,
log[(x^2 - 4) / (x^2 - 4x + 4)] =
log(x^2 - 4) - log(x^2 - 4x + 4)
Simplidied,
log[(x + 2) / (x - 2)] or log(x + 2) - log(x - 2)

= log [ (x - 2).(x + 2) / (x - 2).(x - 2)]
= log [ (x + 2) / (x - 2) ]
= log (x + 2) - log (x - 2)
