Solve with Z-tranform

[emicho]

Hello everybody,
Can anyone just solve this difference equation to me by z-transform till get the last shape of H(Z) after partial fraction....

y-1/4 y(n-1) +1/8 Y(n-2) = x

And thank you Very much

As per I know the H(z) = Y(z)/X(z) = (1/(1-((0.25)*(Z^-1))+((0.125)*(Z^-2))

Good Luck

that's right, but what's the result after doing a partial fraction on H(z)....
