$9 x3 \times 9y2 = 9$
प्लीज मुझे इसका उत्तर दीजिए ​

Answer 1

Step-by-step explanation:

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)

Hope its help.
