Answer 2

It seems like you have provided a mathematical expression:

A^2 - 4a + 4 / 2 - a - (a - 3)^2 / 3 - a

Let's simplify this step by step:

1. A^2 - 4a + 4 is a quadratic expression.
2. (a - 3)^2 is also a quadratic expression.
3. Combine the terms involving 'a'.

So, the expression becomes:

A^2 - 4a + 4 / 2 - a - a^2 + 6a - 9 / 3 - a

Combine like terms:

A^2 - a^2 - 4a + 6a + 4 / 2 - 9 / 3 - a

Simplify further:

A^2 - a^2 + 2a - 5 / 2 - 3 / 3 - a

Now, deal with the divisions:

A^2 - a^2 + 2a - 5 / 2 - 1 - a

Combine the constants:

A^2 - a^2 + 2a - 6 - a

Simplify:

A^2 - a^2 + a - 6

Finally, we can't simplify this expression any further without more context or specific values for 'A' and 'a'. If you have specific numerical values for 'A' and 'a', you can substitute them in to get a numerical result.
