Answer:
36x²y² + 81y² + 108xy² (Real)
4x² + 12x + 9 (Simplified)
Step-by-step explanation:
We can solve this question by using identity (x + y)² = x² + y² + 2xy.
(x + y)² = (6xy + 9y)²
Comparing, x = 6xy and y = 9y
=> (6xy + 9y)² = (6xy)² + (9y)² + 2(6xy)(9y)
=> 36x²y² + 81y² + 108xy² [This is the real expansion.]
Divide the whole equation by 9y².
=> 4x² + 12x + 9 [This is the simplified expansion]
