Determine the response y(n), n 0 of the system described by the second-order difference equation y(n)

Question:

Determine the response y(n), n ≥ 0 of the system described by the second-order difference equation
y(n) – 4y(n - 1) + 4y(n - 2) = x(n) – x(n - 1)
when the input is
x(n) = (–1)nu(n)
and the initial conditions are y(–1) = y(–2) = 0.
