infoWhy this? Extending binomial expansion to fractional and negative powers gives students powerful local approximations and sharper algebraic insight. Numerical methods show how roots and other solutions can be approximated systematically when exact methods are unavailable.

scheduleWhy now? Binomial Expansion is sequenced after the Year 12 foundation and year 13 algebra, when students are ready to generalise the theorem and use it more flexibly. After substantial work on functions, graphs and calculus, students can judge why a numerical approach is needed and how it behaves.
