You asked:

Evaluate the expression: \(\frac{\left(6 + i\right) \cdot \left(2 - i\right)}{\left(4 + 3 i\right) \cdot \left(1 - 2 i\right)}\)

MathBot Answer:

Evaluated



\(\displaystyle \frac{\left(6 + i\right) \cdot \left(2 - i\right)}{\left(4 + 3 i\right) \cdot \left(1 - 2 i\right)} = \frac{\left(1 + 2 i\right) \left(2 - i\right) \left(4 - 3 i\right) \left(6 + i\right)}{125} \)


Expanded

\[\frac{\left(6 + i\right) \cdot \left(2 - i\right)}{\left(4 + 3 i\right) \cdot \left(1 - 2 i\right)} = \frac{6}{5} + \frac{i}{5}\]


Factored

\[\frac{\left(6 + i\right) \cdot \left(2 - i\right)}{\left(4 + 3 i\right) \cdot \left(1 - 2 i\right)} = \left(\frac{1}{125} + \frac{2 i}{125}\right) \left(2 - i\right) \left(4 - 3 i\right) \left(6 + i\right)\]


\(i\) is the imaginary unit, defined as \(i^2 = -1\).
