Question

12(3x-2y)²-3x+2y-1 ​

Answer 1

Answer:Step-by-step explanation:

12a^2-4a+3a-1

4a(3a-1)+1(3a-1)  =(3a-1)(4a+1)

then a=1/3, a=-1/4

now, 3x-2y=1/3

9x-6y=1.

in this way

12x-8y=-1.

and the factor will be

= (9x-6y-1)(12x-8y+1)

Answer 2

Answer : (9x - 6y - 1)(12x - 8y + 1)

Solution :

12(3x - 2y)² - 3x + 2y - 1

=> 12(3x-2y)² - (3x - 2y) - 1

Let, 3x - 2y = t

=> 12t² - t - 1

=> 12t² - 4t + 3t - 1

=> 4t(3t - 1) + 1(3t - 1)

=> (3t - 1)(4t + 1)

On putting the value of t :

=> [3(3x-2y) - 1][4(3x - 2y) + 1]

=> (9x - 6y - 1)(12x - 8y + 1)

I hope it will be helpful for you ☺️
