MathBot Answer:
Evaluated
\(\displaystyle \left(x - 3\right) \cdot \left(4 x - 3\right) - 2 \cdot {x}^{2} + 18 = - 2 x^{2} + \left(4 x - 3\right) \left(x - 3\right) + 18 \)
Expanded
\[\left(x - 3\right) \cdot \left(4 x - 3\right) - 2 \cdot {x}^{2} + 18 = 2 x^{2} - 15 x + 27\]
Factored
\[\left(x - 3\right) \cdot \left(4 x - 3\right) - 2 \cdot {x}^{2} + 18 = \left(2 x - 9\right) \left(x - 3\right)\]
