To evaluate the expression \( 4cd \) for \( c = -1 \) and \( d = 2 \), we substitute the values of \( c \) and \( d \) into the expression.
\[
4cd = 4 \cdot (-1) \cdot 2
\]
Now, perform the multiplication step by step:
1. Calculate \( 4 \cdot (-1) \):
\[
4 \cdot (-1) = -4
\]
2. Then multiply that result by \( 2 \):
\[
-4 \cdot 2 = -8
\]
Therefore, the value of \( 4cd \) is \( \boxed{-8} \).
\[
4cd = 4 \cdot (-1) \cdot 2
\]
