Ex2.1 Q1,3 & 4

Ex3.1 Q3

Mr H, on Monday 20 September, 2010 at 11:32 said:Tuesday 21 September, period 1Further practice on common factors with expressions

Ex4.1 Q2 & 3

Mr H, on Tuesday 21 September, 2010 at 15:14 said:Wednesday 22 September, period 3Look for patterns in multiplying out double brackets (coefficients of x² = 1)

Try and derive a method for factorising a simple trinomial.

Start Ex6.1

Mr H, on Wednesday 22 September, 2010 at 23:49 said:Thursday 23 September, period 5Practice factorising – continue Ex6.1

Mr H, on Sunday 26 September, 2010 at 22:22 said:Monday 27 September, period 6Recap factorising simple trinomials.

Reinforce “…looking for factors of .. and .. that have a sum/difference of…”

Look at expanding examples where the coefficient of x² is greater than 1 and see how we adapt our current method.
