Find the inverse z-transform x[n] of X(z) = (-2z+6z^2)/(-z^2+2z^3) of the first 4 values starting from 0 (z is a complex variable)
Compute inverse z-transform of X(z) = (1 + 2z-1 + z-2)/ (1 - z-1 + 0.3561z-2) by expanding into a power series using long division. You can stop at the first four terms (Basically, get x(0), x(1), x(2) and x(3)). [10 points].
