5(3x-1) (x-3)(x-2) I don't know if you want working out or an explanation? Or if it's too late, sorry.

Answer 2

❶ Factorise :- 15x - 5

Solution :-

• Factor out 5 from the given Expression

→ 5(3x - 1)

________________

❷ Factorise :- x² - 5x + 6

Solution :-

→ x² - 5x + 6

• Rewrite -5x as a difference

→ x² - 2x - 3x + 6

• Factor out x form the expression

→ x × (x - 2) - 3x + 6

• Factor out -3 form the expression

→ x × (x - 2) - 3 (x -2)

• Factor out x-2 from the expression

→ (x - 2) × (x - 3)
