Answer:
C
Step-by-step explanation:
The general formula for the binomial expansion is
(n over k) * (x)^(n - k) * y^k
n = 8
k = 2 which is the third term. That's because k starts at 0.
n over k = n C k = 8 C 2 = 8!/(8-2)! * 2!
2^2 = 4
n over k = 8!/(6!)(2!) = 8*7 / 2 = 28
x^(n - k) = x^(8 - 2) = x ^6
So the result is
x^6 * 28 * 2^2
112 x^6
The answer is C
