Answer 3

To simplify the expression, let's expand it step by step:

Expression: (4a + 3)^2 - (2a + 1)(4a - 3)

Step 1: Expand (4a + 3)^2 (4a + 3)^2 = (4a + 3) * (4a + 3) = 16a^2 + 24a + 9

Step 2: Expand (2a + 1)(4a - 3) (2a + 1)(4a - 3) = 8a^2 - 6a + 4a - 3 = 8a^2 - 2a - 3

Now, we have the simplified expression: (4a + 3)^2 - (2a + 1)(4a - 3) = (16a^2 + 24a + 9) - (8a^2 - 2a - 3)

Step 3: Distribute the negative sign to the second expression: (16a^2 + 24a + 9) - (8a^2 - 2a - 3) = 16a^2 + 24a + 9 - 8a^2 + 2a + 3

Step 4: Combine like terms: 16a^2 - 8a^2 = 8a^2 24a + 2a = 26a 9 + 3 = 12

The final simplified expression is: (4a + 3)^2 - (2a + 1)(4a - 3) = 8a^2 + 26a + 12

Please note that this simplified expression might still be factorable further, but this is the most simplified form based on the given expression.
