Question

FACTORISE 4X²-9Y²-2X-3Y​

Answer 1

Answer:

Applying the identity: a

2

−b

2

=(a+b)(a−b)

Using the above identity, the equation 4x

2

−9y

2

−2x−3y can be factorised as follows:

4x

2

−9y

2

−2x−3y=(2x)

2

−(3y)

2

−2x−3y=(2x+3y)(2x−3y)−1(2x+3y)=(2x+3y)(2x−3y−1)

Hence, 4x

2

−9y

2

−2x−3y=(2x+3y)(2x−3y−1)

Answer 2

Answer:

(2x+3y)(2x-3y-1)

Step-by-step explanation:

4x² - 9y² - 2x - 3y

(2x)² - (3y)² - (2x + 3y)

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

(2x +3y) ( 2x - 3y -1 )
