\(\displaystyle 5 - x \cdot \left(\left(2 - x\right) \cdot \left(5 - x\right) - 4\right) + 2 \cdot \left(-\left( 2 \cdot \left(5 - x\right) \right) + 8\right) + 4 \cdot \left(-4 + 4 \cdot \left(2 - x\right)\right) = - x \left(\left(2 - x\right) \left(5 - x\right) - 4\right) - 12 x + 17 \)
Expanded
\[5 - x \cdot \left(\left(2 - x\right) \cdot \left(5 - x\right) - 4\right) + 2 \cdot \left(-\left( 2 \cdot \left(5 - x\right) \right) + 8\right) + 4 \cdot \left(-4 + 4 \cdot \left(2 - x\right)\right) = - x^{3} + 7 x^{2} - 18 x + 17\]
Factored
\[5 - x \cdot \left(\left(2 - x\right) \cdot \left(5 - x\right) - 4\right) + 2 \cdot \left(-\left( 2 \cdot \left(5 - x\right) \right) + 8\right) + 4 \cdot \left(-4 + 4 \cdot \left(2 - x\right)\right) = - x^{3} + 7 x^{2} - 18 x + 17\]
