Step-by-step explanation:
(1) 12x2 −7x+1
=12x 2−4x−3x+1
=4x(3x−1)−1(3x−1)
=(4x−1)(3x−1)
(2) 3x2−x−4
=3x2−4x+3x−4
=x(3x−4)+1(3x−4)
=(3x−4)(x+1)

Step-by-step explanation:
i) 12x² - 7x +1
= 12x² -3x -4x +1
= 3x (4x - 1) - 1(4x - 1)
= (3x-1)(4x-1) --------------------Ans
ii) 3x² -x - 4
= 3x² -4x +3x -4
= x(3x -4) + 1(3x -4)
= (3x- 4) (x+1) ----------------- Ans
