Derivation

  1. Initial program 0.1

    \[\left(\left(\left(27 \cdot {x}^{4} + 1792 \cdot {x}^{3}\right) + 2592 \cdot {x}^{2}\right) - 324 \cdot x\right) - 243\]

  2. Final simplification0.1

    \[\leadsto \left(\left(\left(27 \cdot {x}^{4} + 1792 \cdot {x}^{3}\right) + 2592 \cdot {x}^{2}\right) - 324 \cdot x\right) - 243\]
