Derivation

  1. Initial program 33.5

    \[\sqrt{\left(\left(\left(s - a\right) \cdot \left(s - b\right)\right) \cdot \left(s - c\right)\right) \cdot \left(s - c\right)}\]

  2. Final simplification33.5

    \[\leadsto \sqrt{\left(\left(\left(s - a\right) \cdot \left(s - b\right)\right) \cdot \left(s - c\right)\right) \cdot \left(s - c\right)}\]
