Question
The largest coefficient in the expansion of (1 + x)30 is ______.
Solution
The largest coefficient in the expansion of (1 + x)30 is 30C15.
Explanation:
Here n = 30 which is even
∴ The largest coefficient in (1 + x)n = `""^n"C"_(n /2)`
So, the largest coefficient in (1 + x)30 = 30C15
Hence, the value of the filler is 30C15.
