What this AA HL binomial theorem worksheet covers

Expanding (a + b)ⁿ, finding specific terms and coefficients, and using Pascal's triangle and nCr. The questions follow the order of the AA HL syllabus for Topic 1 (Number & Algebra) and are graded in three bands — routine practice, exam-standard, and the harder multi-step questions that separate a 6 from a 7.

General term of a binomial expansion
Finding the coefficient of a given power of x
Expansions with negative or fractional terms inside the bracket
Approximation using the first few terms
Exam tip for this topic. Write the general term with the index first, then solve for the power you need — never expand everything.

How to use it

  1. Do the first band without the AA HL formula booklet, then check which formulas you had to look up — those are the ones to memorise.
  2. Time the second band at roughly 1.2 minutes per mark, the pace of Paper 1 and Paper 2.
  3. For the third band, compare your method with the matching questions in the AA HL question bank; if you want this set marked, send it to Mr Ahmad.
