Derivation

  1. Initial program 33.8

    \[\frac{\frac{\left(\left(a + b\right) + c\right) \cdot \left(\left(a + b\right) - c\right)}{a}}{b} - 2\]

  2. Final simplification33.8

    \[\leadsto \frac{\frac{\left(\left(a + b\right) + c\right) \cdot \left(\left(a + b\right) - c\right)}{a}}{b} - 2\]
