Answer:

15z^2 + 47z

Explanation:

To solve this equation, we need to simplify and combine like terms. First, let's distribute the terms within the parentheses:

8z - 5z(4z - 2(3z - 6)) - 7z(-5z + 3)

= 8z - 20z^2 + 30z - 5z(-6z + 12) - 7z(-5z + 3)

= 8z - 20z^2 + 30z + 30z - 20z + 35z^2 - 21z

Next, we can combine like terms:

8z - 20z^2 + 30z + 30z - 20z + 35z^2 - 21z

= -20z^2 + 35z^2 + 8z - 20z + 30z + 30z - 21z

= 15z^2 + 47z

Therefore, 8z - 5z(4z - 2(3z - 6)) - 7z(-5z + 3) simplifies to 15z^2 + 47z.
