QUESTION: FACTORIZE: 6a2 - a-15 Question : FACTORIZE : 12(3x - 2y)2 - 3x + 2y - 1

Answer 1

 12(3x−2y)  

2

−3x+2y−1

Let (3x−2y) be a

=12a  

2

−a−1

=12a  

2

−4a+3a−1

=4a(3a−1)+1(3a−1)

=(3a−1)(4a+1)

Putting the value of a

[3(3x−2y)−1][4(3x−2y)+1]

=(9x−6y−1)(12x−8y+4)

Answer 2

Step-by-step explanation:

(3x-2y+5) (3x-2y-2)
