Simplify: (X & sup2; - 4x + 4 / 4 x & sup2; - X-2 / 2) / X-2 / 2, then choose any number you like to substitute into the evaluation!

Simplify: (X & sup2; - 4x + 4 / 4 x & sup2; - X-2 / 2) / X-2 / 2, then choose any number you like to substitute into the evaluation!

=[x²/(x-2)²-x/(x-2)]×(x-2)/x
=X / (X-2) - 1 multiplicative distributive law
=x/(x-2)-(x-2)/(x-2)
=2/(x-2)
When x = 3
Original formula = 2 / (3-2) = 2
