Question

Find the coefficient of x^{8} in the expansion of (x + 2)^{11}.

- 640
- 326
- 1320
- 456

## The correct answer is: 1320

### STEP BY STEP SOLUTION

The coefficient of the 8^{th} term is ^{11}C_{8} = 165.

Hence, the 8^{th} term of the expansion is 165 × 2^{3} × x^{8} = 1320x^{8},

where the coefficient is 1320.
