\(\frac{(\left((\left((y * x + z)_*\right) * \left({y}^2\right) + \left((y * 27464.7644705 + 230661.510616)_*\right))_*\right) * y + t)_*}{(\left({y}^2\right) * \left((\left(y + a\right) * y + b)_*\right) + \left((y * c + i)_*\right))_*}\)
  1. Started with
    \[\frac{\left(\left(\left(x \cdot y + z\right) \cdot y + 27464.7644705\right) \cdot y + 230661.510616\right) \cdot y + t}{\left(\left(\left(y + a\right) \cdot y + b\right) \cdot y + c\right) \cdot y + i}\]
    28.3
  2. Applied simplify to get
    \[\color{red}{\frac{\left(\left(\left(x \cdot y + z\right) \cdot y + 27464.7644705\right) \cdot y + 230661.510616\right) \cdot y + t}{\left(\left(\left(y + a\right) \cdot y + b\right) \cdot y + c\right) \cdot y + i}} \leadsto \color{blue}{\frac{(\left((\left((y * x + z)_*\right) * \left(y \cdot y\right) + \left((y * 27464.7644705 + 230661.510616)_*\right))_*\right) * y + t)_*}{(\left(y \cdot y\right) * \left((\left(y + a\right) * y + b)_*\right) + \left((y * c + i)_*\right))_*}}\]
    28.6
  3. Applied simplify to get
    \[\frac{\color{red}{(\left((\left((y * x + z)_*\right) * \left(y \cdot y\right) + \left((y * 27464.7644705 + 230661.510616)_*\right))_*\right) * y + t)_*}}{(\left(y \cdot y\right) * \left((\left(y + a\right) * y + b)_*\right) + \left((y * c + i)_*\right))_*} \leadsto \frac{\color{blue}{(\left((\left((y * x + z)_*\right) * \left({y}^2\right) + \left((y * 27464.7644705 + 230661.510616)_*\right))_*\right) * y + t)_*}}{(\left(y \cdot y\right) * \left((\left(y + a\right) * y + b)_*\right) + \left((y * c + i)_*\right))_*}\]

  4. Applied simplify to get
    \[\frac{(\left((\left((y * x + z)_*\right) * \left({y}^2\right) + \left((y * 27464.7644705 + 230661.510616)_*\right))_*\right) * y + t)_*}{\color{red}{(\left(y \cdot y\right) * \left((\left(y + a\right) * y + b)_*\right) + \left((y * c + i)_*\right))_*}} \leadsto \frac{(\left((\left((y * x + z)_*\right) * \left({y}^2\right) + \left((y * 27464.7644705 + 230661.510616)_*\right))_*\right) * y + t)_*}{\color{blue}{(\left({y}^2\right) * \left((\left(y + a\right) * y + b)_*\right) + \left((y * c + i)_*\right))_*}}\]
