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
