Question
Find the coefficient of x^4 in the binomial expansion of (1 - 2x)^6
Correct Answer
Option E is the correct answer.
Detailed Explanation
Using the binomial theorem, the general term is C(6, r)(-2x)^r. For x^4, r = 4: C(6,4)(-2)^4 = 15 × 16 = 240. Hence, the coefficient of x^4 is 240.
Hint
Use the general term C(n, r)(ax)^r and select r = 4.
