A) \[\frac{(2n)!}{{{(n!)}^{2}}}\]
B) \[\frac{(2n+2)!}{{{\{(n+1)!\}}^{2}}}\]
C) \[\frac{(2n+2)!}{n!(n+1)!}\]
D) \[\frac{(2n)!}{n!(n+1)!}\]
Correct Answer: B
Solution :
Greatest coefficient of \[{{(1+x)}^{2n+2}}\] is \[={{\,}^{(2n+2)}}{{C}_{n+1}}=\frac{(2n+2)!}{{{\{(n+1)!\}}^{2}}}\]You need to login to perform this action.
