Let's simplify the expression $-9(8a - 2)$:

1. Distribute $-9$ to both terms inside the parentheses: $-9 \times 8a = -72a$ $-9 \times -2 = 18$

2. Combine the results: $-72a + 18$

So, the simplified expression is: $-72a + 18$

Would you like any more details or have any questions? Here are five related questions to consider:

1. How would you simplify $-7(3b - 4)$?
2. Can you distribute and simplify $-6(5c + 7)$?
3. What is the result of $-4(2x - 9)$?
4. How do you handle distribution when the coefficient is positive instead of negative?
5. Can you factor the expression $-72a + 18$ back to its original form?

Tip: Always remember that when distributing a negative number, the signs of the terms inside the parentheses will change accordingly.
