There are some errors in your solutions. Let me provide the correct solutions using the Cube of a Binomial formula:
1. (a + 2)³ = a³ + 3a²(2) + 3a(2)² + 2³
= a³ + 6a² + 12a + 8
Therefore, the correct expansion of (a + 2)³ is a³ + 6a² + 12a + 8.
2. (3x - 2)³ = (3x)³ - 3(3x)²(2) + 3(3x)(2²) - 2³
= 27x³ - 54x² + 36x - 8
Therefore, the correct expansion of (3x - 2)³ is 27x³ - 54x² + 36x - 8.
