Outcomes
8.A.AE.1
Multiplication and division of algebraic exp.(Coefficient should be integers)
8.A.AE.2
Some common errors (e.g. 2 + x ≠ 2x, 7x + y ≠ 7xy )
8.A.AE.3
Identities (a ± b)^2 = a^2 ± 2ab + b^2, a^2 – b^2 = (a – b) (a + b) Factorisation (simple cases only) as examples the following types a(x + y), (x ± y)^2, a^2 – b^2, (x + a).(x + b)
