Answer 2

Let's simplify each of the given expressions:

1. (a-b)^2 + a-b

First, expand the square: (a-b)^2 = a^2 - 2ab + b^2

Now, add a-b: a^2 - 2ab + b^2 + a - b

Combine like terms: a^2 + a - 2ab - b^2 - b

2. 4q(p-1) + (p-1)^2

Expand the square: (p-1)^2 = p^2 - 2p + 1

Now, add 4q(p-1): 4qp - 4q + p^2 - 2p + 1

Combine like terms: p^2 + 4qp - 2p - 4q + 1

3. 4q(p-1) + p-1

Combine like terms: 4qp - 4q + p - 1

4. 4q(p-1) + 1-p

Combine like terms: 4qp - 4q + 1 - p

5. a(b+c) + db + dc

Distribute a: ab + ac + db + dc

6. 2x(3x-4y) - 6x + 8y

First, distribute 2x: 6x^2 - 8xy - 6x + 8y

Now, combine like terms: 6x^2 - 6x - 8xy + 8y

These are the simplified forms of the given expressions.
