Factorising Review all the methods

Factorise using a non Monic method

2x² - 5x - 3

• (2x + 1) (x - 3)

• (2x - 1) (x + 3)

• (2x - 1) (x + 6)

• (x + 1) (2x - 3)

Factorise using a non monic method

6x² + 7x - 3

• (3x - 1) (2x + 3)

• (3x + 1) (2x - 3)

• (6x + 1) (x - 3)

• (2x + 1) (3x - 3)

Factorise this monic trinomial):

x² - 2x - 15

• (x - 5)(x + 3)

• (x + 3)(x - 5)

• (x - 3)(x - 5)

• (x - 15)(x - 2)

Factorise using HCF

12x + 9

• 3 (4x + 3)

• x (12+9)

• 3 (4x - 3)

• Prime

Factorise using HCF

18a² - 15a

• 15a (3a - 1)
