To evaluate the expression \( u - v \) and \( uv - v \) for \( u = 4 \) and \( v = -2 \), we'll start by calculating each component step by step.
1. **Calculate \( u - v \)**:
\[
u - v = 4 - (-2) = 4 + 2 = 6
\]
2. **Calculate \( uv - v \)**:
\[
uv = 4 \times (-2) = -8
\]
Then,
\[
uv - v = -8 - (-2) = -8 + 2 = -6
\]
Now we combine both results:
- The result for \( u - v \) is \( 6 \).
- The result for \( uv - v \) is \( -6 \).
So the final simplified answer for the expressions is:
\[
u - v = 6
\]
\[
uv - v = -6
\]
