To determine the difference between complex number:


(-1-5i)-(5-7i_{})

Step 1: Remove the bracket and find the difference


\begin{gathered} (-1-5i)-(5-7i_{}) \\ -1-5i-(5-7i_{}) \\ -1-5i-5+7i_{} \end{gathered}

Step2: Collect like terms


\begin{gathered} (-1-5i)-(5+7i_{}) \\ (-1-5i)-(5+7i_{} \\ -1-5-5i+7i \\ -6+2i \\ 2i-6 \end{gathered}

Hence the final answer is 2i - 6
