Mixed Binomial Expansion A level

Mixed questions for binomial expansion, covering a variety of question styles, and mixing up positive integer, and fractional and negative indices. Previously, these types of questions would be assessed separately under the old module system, but with the new A level, they will be mixed up, and students will need to select the correct method of expansion. Although the general form works for all, there are some questions for which this is not the most appropriate method.
