Algebra PowerPoint Presentation

Brackets and Factorising 2

A PowerPoint math/maths presentation covering expansion of brackets and factorisation.

We look at harder bracket expansion and some factorisation in this presentations. Moving on from brackets 1 we introduce a variable outside the bracket and end up with non-linear terms including cubics.

On expanding double brackets you have a choice of methods to use.
1. Turn them into two single and expand
2. Use a FOIL type method to end up with 4 terms and simplify to a trinoimial.
3. Expand directly by inspection
You can mix and match the various methods to suit your group.

Note that factorisation of the general quadratics is not covered in this presentation (see quadratics1 factorisation).
