Question

Find the term independent of x
in the expansion( x-1/x)^14​

Answer 1

Step-by-step explanation:

first take out the general term and then equate all the coefficient of x to zero because it has asked the independent term

Answer 2

Answer:

7th term

Step-by-step explanation:

t↓r+1=14!/{r!(14-r!)}*x^(14-r)*1/x^r(-1)^r

→14!/{r!(14-r)!}*x^(14-r-r)

since,term is independent of x so power of x will be zero

so,

→14-r-r=0

→14-2r=0

→r=7
