$(ni-n+3)^{2}$
You asked:
Evaluate the expression: \({\left( n i - n + 3 \right)}^{2}\)
MathBot Answer:
Evaluated
\(\displaystyle {\left( n i - n + 3 \right)}^{2} = \left(- n + n i + 3\right)^{2} \)
Expanded
\[{\left( n i - n + 3 \right)}^{2} = - 2 n^{2} i - 6 n + 6 n i + 9\]
Factored
\[{\left( n i - n + 3 \right)}^{2} = \left(n \left(1 - i\right) - 3\right)^{2}\]
\(i\) is the imaginary unit, defined as \(i^2 = -1\).
