Factorisation 10r – 25f = 28t + 14s = 50u – 75v = 6d – 12f + 9e = Factorisation is the reverse process of expanding brackets. Find the highest number that divides into each number term. 10r – 25f = 28t + 14s = 50u – 75v = 6d – 12f + 9e = 5 (2r – 5f) 14 ( 2t + s) 25 ( 2u – 3v) 3 (2d – 4f + 3e)

Factorise the following expressions: 1. 6f + af = 2. ab – 8b = 3. 2dp + 14pr = 4. 10gh – 15hk = 24st + 8sy = 5ab – 2bc =

This means that letter terms can also be factors and used to factorise an expression.

Factorise the following expressions: 1. f2 + 6f = 2. b2 – 8b = Common Factors Factorise the following expressions: 1. f2 + 6f = 2. b2 – 8b = 3. 4p2 + 14p = 4. 10w2 – 15w = 24x2 + 8x = 5ab – 2bc = f ( f + 6) b (b – 8) 2p (2p + 7) 5w (2w – 3) 8x (3x + 1) b ( 5a – 2c)
