(3x+2y)² + (3x-2y)² simplify using the identity​

Sure, let's simplify the expression using the identity.

The given expression is (3x+2y)² + (3x-2y)².

Let's simplify it step by step:

Step 1: Expand the squares

= (9x² + 12xy + 4y²) + (9x² - 12xy + 4y²)

Step 2: Combine like terms

= 9x² + 9x² + 12xy - 12xy + 4y² + 4y²

Step 3: Simplify

= 18x² + 8y²

So, (3x+2y)² + (3x-2y)² simplifies to 18x² + 8y².
