log(x + 1)                                     
---------- - log(x + 1)                        
  log(4)                  log(1 - x)    log(25)
----------------------- - ---------- <= -------
       log(1 - x)          log(25)       log(4)
$$\frac{- \log{\left(x + 1 \right)} + \frac{\log{\left(x + 1 \right)}}{\log{\left(4 \right)}}}{\log{\left(1 - x \right)}} - \frac{\log{\left(1 - x \right)}}{\log{\left(25 \right)}} \leq \frac{\log{\left(25 \right)}}{\log{\left(4 \right)}}$$
(-log(x + 1) + log(x + 1)/log(4))/log(1 - x) - log(1 - x)/log(25) <= log(25)/log(4)
