Answer 3

To expand the expression A2-4a-(a+4a+4), we can follow these steps:

1. Distribute the negative sign to each term inside the parentheses.
2. Combine like terms.

Let's start:

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

Step 1: Distribute the negative sign:

A^2 - 4a - a - 4a - 4

Step 2: Combine like terms:

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

Now, add the coefficients of 'a':

A^2 - (9a) - 4

Finally, the expanded expression is:

A^2 - 9a - 4
