Q9. In the expansion of , prove that coefficients of and are equal
As we know that the general term in the binomial expansion of is given by
So, the general term in the binomial expansion of is given by
Now, as we can see will come when and will come when
So,
Coefficient of :
CoeficientCoefficient of :
As we can see .
Hence it is proved that the coefficients of and are equal.
