Question

4. Factorise :
(1) 12x2 - 7x + 1
(ii) 6x2 + 5x--6

Answer 1

Answer:

(1) (6x - 1)(x - 1)(2x - 1)

(2) (x + 1)(6x - 1)

Step-by-step explanation:

(1) $12x^{2}$ - 7x + 1

 = $12x^{2}$ - 6x - x + 1

 = 6x(2x - 1) - 1(x - 1)

 = (6x - 1)(x - 1)(2x - 1)

(2) $6x^{2}$ + 5x - 6

   = $6x^{2}$ + 6x - x - 6

   = 6x(x + 1) - 1(x + 1)

   = (x + 1)(6x - 1)
