Answer 3

To evaluate the expression $(2-c)^2 - c(c+4)$ when $c = 2$, you substitute $c$ with 2 in the expression and then simplify.

1. Substitute $c = 2$ into the expression: $(2 - 2)^2 - 2(2 + 4)$

2. Simplify inside the parentheses and the exponent: $0^2 - 2(6)$

3. Multiply: $0 - 12$

4. Finally, the result is $-12$.
