Let 'A' denotes the real part of the complex number `z=(19+7i)/(9-i)+(20+5i)/(7+6i)` and 'B' denotes the sum of the imaginary parts of the roots of the equation `z^2 – 8(1 – i)z + 63 – 16i = 0` and 'C' denotes the sum of the series, `1 + i + i^2 + i^3 + ..... + i^(2008)` where `i =sqrt(-1)` and D' denotes the value of the product `(1+omega)(1+omega^2)(1+omega^4)(1-omega^8)` where `omega` is the imaginary cube root of unity . Find the value of `(A-B)/(C+D)`
