Bits error versus x

Derivation

  1. Initial program 0.0

    \[\frac{1}{x - 1} + \frac{x}{x + 1}\]
  2. Using strategy rm

  3. Applied add-cbrt-cube0.0

    \[\leadsto \color{blue}{\sqrt[3]{\left(\frac{1}{x - 1} \cdot \frac{1}{x - 1}\right) \cdot \frac{1}{x - 1}}} + \frac{x}{x + 1}\]

  4. Applied simplify0.0

    \[\leadsto \sqrt[3]{\color{blue}{\frac{\frac{1}{x - 1}}{\left(x - 1\right) \cdot \left(x - 1\right)}}} + \frac{x}{x + 1}\]
  5. Removed slow pow expressions.
