Find the term independent of x in the expansion of(x-1/x) ^12​

Answer»

Answer:

So 7TH TERM will be independent of x.

Step-by-step explanation:

By USING binomial expansion,

We GET 12Cr(x)^[12–r]×1/x^r

So term independent of x means

12–r–r=0 {ie.The power of x should be 0}

So r=6

So the REQ. Term will be (r+1)th term so answer will be 7th term.

I hope it helps you.☺
