Answer:

Correct question :-

➠ (2a + 3b)² + 2(2a + 3b)(2a - 3b) + (2a - 3b)²

Formula used :-

➪ a² + 2ab + b²

➭ (a + b)²

Answer :-

➠ (2a + 3b)² + 2(2a + 3b)(2a - 3b) + (2a - 3b)²

➻ x² + 2xy + y² [Taking 2a + 3b = x, 2a - 3b = y]

➻ (x + y)²

➻ (2a + 3b + 2a - 3b)² [Putting the value of x = 2a + 3b, y = 2a - 3b]

➻ (2a + 2a + 3b - 3b)²

➻ (4a)²

➻ 16a²

∴ The value of (2a + 3b)² + 2(2a + 3b)(2a - 3b) + (2a - 3b)² is 16a²
