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
