Find the term independent of x in the expansion of :



To Find : term independent of x, i.e. x0


For


, and n=6


We have a formula,








Now, to get coefficient of term independent of xthat is coefficient of x0 we must have,


(x)12-3r = x0


• 12 - 3r = 0


• 3r = 12


• r = 4


Therefore, coefficient of x0


………




Conclusion : coefficient of x0
