Answer 2

Answer 3

To simplify the expression by expanding the brackets, let's apply the distributive property:

3ab - 3a - (a - 3ab)

When we remove the parentheses, we need to distribute the negative sign to each term inside the parentheses:

3ab - 3a - a + 3ab

Now let's combine like terms:

(3ab + 3ab) - 3a - a

6ab - 3a - a

Finally, we can simplify further:

6ab - 4a

So, the simplified expression after expanding the brackets is 6ab - 4a.
