Question

(1) (2x + 3y)(2x - 3y)​

Answer 1

Answer:

4x^2 - 8xy + 6xy - 9y^2

=> 4x^2 - 2xy - 9y^2

hope that helps ✌

Answer 2

Step-by-step explanation:

Given (2x-3y) (2x-3y)

But we can write the given expression as (2x – 3y) (2x -3y) = (2x – 3y)²

But we have (a – b)²=a²-2ab+b²

On applying above identity in the given expression we get,

(2x – 3y)² = 4x²-2 (2x) (3y) + 9y²

(2x – 3y)² = 4x²-12 xy + 9y²
