Chapter 19 - Equations and formulae

	The key ideas for this chapter: Solving quadratic equations by factorisation.  Rearranging equations, including examples where you have to factorise.
	At college: You can practise multiplying out brackets and factorising by using the Virtual Image algebra program.  This is accessible from all the computers at Birley CC.  Click Start -> All programs -> Core Programs > CD-ROM Player > Virtual Image Algebra

	Solving quadratic equations by factorising  Watch a presentation and practise some questions to help you with this topic. You don't need sections 8 and 9 of this presentation for this module. from mymaths,co.uk   Requires you to log in - why? Also requires Adobe Flash Player - what's this?
	OR Solving quadratic equations by factorising - Continues the work from chapter 17 but DON'T click next - this takes you to work that is not needed for this module. from bbc.co.uk
