=(x^2-4)/(2x-4)
Factor out a 2 in the denominator, so we get
=(x^2-4)/2(x-2)
Expand the numerator into 2 brackets, so we get
=(x-2)(x+2)/2(x-2)
=x+2/2 is your simplest form

Factor out a 2 from the bottom. Factor the top into (x+2)(x-2). You'll then find that you can cancel out a (x-2) term. Write the simplified expression.

x*2-4 =(x-2)(x+2)
2x-4 =2(x-2)
cancelling out the x-2 from top and bottom of your fraction you get (x+2)/2 or (x/2)+1

(x^2 - 4) / (2x - 4)
= (x - 2)(x + 2) / 2(x - 2)
= (x + 2) / 2
= (x/2 + 1)
