Question

Expand using the identity ( 2x + 3y)^2 – (2x – 3y)^2. Pls don't answer if you don't know

Answer 1

Answer:

(2x)^2 - (3y)^2

= 4×^2 - 9y^2

Answer 2

Answer:

24xy

Step-by-step explanation:

(2x + 3y)² - (2x-3y)²

= 4 (2x) (3y)

= 24 x y

Using the identity:

Using the identity:(a+b)² - (a-b)² = 4ab
