Dear manan
(1+x3)(1-x+x^2) /(1-x2)(1-x)
=(1+x3)2/(1-x2)2
=(1+x3)2(1-x2)-2
coeffient of x12 = coeffient of X0 in first bracket * coeffient of X12 in second bracket
+coeffient of X6 in first bracket * coeffient of X6 in second bracket
+coeffient of X12 in first bracket * coeffient of X0in second bracket
calculete it and put the value
