Answer 3

To simplify the given expression, let's go step by step:

$3a(a-2)-(a-2)(3a-1)-a$

Step 1: Expand the terms within the parentheses.

$= 3a^2 - 6a - (3a^2 - 7a + 2)$

Step 2: Distribute the negative sign across the second set of parentheses.

$= 3a^2 - 6a - 3a^2 + 7a - 2 - a$

Step 3: Combine like terms.

$= (3a^2 - 3a^2) + (-6a + 7a - a) - 2$

$= 0 + 0 - 2$

Step 4: Simplify the result.

$= -2$

So, the simplified form of the given expression is $-2$.
