Derivation

  1. Initial program 0.1

    \[\left(\left(15 \cdot {x}^{3} + 2.10000000000000009 \cdot {x}^{2}\right) - 3.56000000000000005 \cdot x\right) + 2\]

  2. Final simplification0.1

    \[\leadsto \left(\left(15 \cdot {x}^{3} + 2.10000000000000009 \cdot {x}^{2}\right) - 3.56000000000000005 \cdot x\right) + 2\]
