Answer
The standard form of the expression $\left( 6-2i \right)-\left( 7-i \right)$ is $-1-i$.
Work Step by Step
Consider the expression, $\left( 6-2i \right)-\left( 7-i \right)$
Remove the parentheses.
$\left( 6-2i \right)-\left( 7-i \right)=6-2i-7+i$
Combine the real part and the imaginary part.
$\begin{align}
& \left( 6-2i \right)-\left( 7-i \right)=\left( 6-7 \right)+\left( 1-2 \right)i \\
& =-1-i
\end{align}$
Therefore, the standard form of the expression $\left( 6-2i \right)-\left( 7-i \right)$ is $-1-i$.
