(6i)(6 − 8i) − 4 ⋅ (−2i)
You asked:
Evaluate the expression: \(6 i \left(6 - 8 i\right) - 4 \cdot -\left( 2 i \right)\)
MathBot Answer:
Evaluated
\(\displaystyle 6 i \left(6 - 8 i\right) - 4 \cdot -\left( 2 i \right) = 8 i + 6 i \left(6 - 8 i\right) \)
Expanded
\[6 i \left(6 - 8 i\right) - 4 \cdot -\left( 2 i \right) = 48 + 44 i\]
Factored
\[6 i \left(6 - 8 i\right) - 4 \cdot -\left( 2 i \right) = 4 i \left(11 - 12 i\right)\]
\(i\) is the imaginary unit, defined as \(i^2 = -1\).
