Step-by-step explanation:
(i) We have,
12x² – 7x + 1
= 12x² – 4x- 3x + 1
= 4x (3x – 1 ) -1 (3x – 1)
= (3x -1) (4x -1)
Thus, 12x² -7x + 3 = (3x -1) (4x -1)
--------------------------------------
(ii) We have, 2x² + 7x + 3
= 2x² + x + 6x + 3
= x(2x + 1) + 3(2x + 1)
= (2x + 1)(x + 3)
Thus, 2x² + 7x + 3 = (2x + 1)(x + 3)
--------------------------------------
(iii) We have, 6x² + 5x – 6
= 6x² + 9x – 4x – 6
= 3x(2x + 3) – 2(2x + 3)
= (2x + 3)(3x – 2)
Thus, 6x² + 5x – 6 = (2x + 3)(3x – 2)
--------------------------------------
(iv) We have, 3x² – x – 4
= 3x²– 4x + 3x – 4
= x(3x – 4) + 1(3x – 4)
= (3x – 4)(x + 1)
Thus, 3x² – x – 4 = (3x – 4)(x + 1)
