Answer 3

Task: Simplify the Expression 4c(c-2)-(c-4)*

To simplify the given expression 4c(c-2)-(c-4)*, we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

1. First, let's simplify the expression within the parentheses: - 4c(c-2) becomes 4c^2 - 8c - (c-4)* becomes (c-4)

2. Now, we can substitute the simplified expressions back into the original expression: - 4c(c-2)-(c-4)* becomes 4c^2 - 8c - (c-4)

3. Finally, we can distribute the negative sign to the terms inside the parentheses: - 4c^2 - 8c - (c-4) becomes 4c^2 - 8c - c + 4

4. Combining like terms, we get the final simplified expression: - 4c^2 - 9c + 4

Therefore, the simplified form of the expression 4c(c-2)-(c-4)* is 4c^2 - 9c + 4.
