Question

Use the binomial theorem to find the 12th term on the binomial expansion of (- 2√x+1/2y)^19

Answer 1

This question is intentionally done to make sure you can manipulate algebraic expressions; it really doesn't help you understand the binomial theorem.

The answer is ₁₉C₁₁ * (-2√x)¹¹(y/2)⁸ where the term with the C is the binomial coefficient. Remember the first term of the binomial theorem has subscript 0.
