Answer 1

Z +11 B + 드 *IN al ->O Z ZZ 2-1 z? (2-1) Z +11 A Z (2-1) + B (2-1) + C(22) z²(2-1) Z?(2-1) Z tll Az(2-1) + B(2-1) +((22) - Put 2-0 B(0-1) +cco) =) 11 = - - B B put z=1 = lit! (D07 (0)8+ (0) + 12 - otc C = 12 compare z? coefficients' on both sides, we get A tc A = -c A - 12 Put all values an we get 12 11 Z +11 2²(2-0 + + Z 32 2-1 Ztu 11 12 - V + 1 2 2 그 z'(2-0) Z2 2-)
