Find the term independent of x in the expansion of :

Answer :

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


a=2x, and n=9

We have a formula,

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

(x)9-3r = x0

• 9 - 3r = 0

• 3r = 9

• r = 3

Therefore, coefficient of x0

Conclusion : coefficient of x0
