- Factors of algebraic expression 4xy = 4 x x x y
- 1 is a factor of every expression.
- Method of common factors
- 4x + 24 = 4(x + 6)
- Method of factorisation by regrouping terms
6xy + 3y = 2 x 3 x x x y + xy = 3 xy (2x + 1) = 3y (2x + 1)

a2 + 2ab + b2– (a + b)2
a2 – 2ab + b2= (a-b)2
a2 – b2 = (a + b) (a – b)
