Question

factories (i) 12x²-7x+1 (ii) 3x²-x-4​

Answer 1

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)

Answer 2

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
