1. Started with
   \[\frac{b \cdot c - a \cdot d}{{c}^2 + {d}^2}\]
   21.7
2. Using strategy rm
   21.7
3. Applied add-sqr-sqrt to get
   \[\frac{b \cdot c - a \cdot d}{{c}^2 + \color{red}{{d}^2}} \leadsto \frac{b \cdot c - a \cdot d}{{c}^2 + \color{blue}{{\left(\sqrt{{d}^2}\right)}^2}}\]
   21.7
4. Applied simplify to get
   \[\frac{b \cdot c - a \cdot d}{{c}^2 + {\color{red}{\left(\sqrt{{d}^2}\right)}}^2} \leadsto \frac{b \cdot c - a \cdot d}{{c}^2 + {\color{blue}{\left(\left|d\right|\right)}}^2}\]
   21.7
5. Applied taylor to get
   \[\frac{b \cdot c - a \cdot d}{{c}^2 + {\left(\left|d\right|\right)}^2} \leadsto \left(\frac{{\left(\left|\frac{-1}{d}\right|\right)}^2 \cdot \left(d \cdot a\right)}{{c}^{4}} + \frac{b}{c}\right) - \frac{d \cdot a}{{c}^2}\]
   6.2
6. Taylor expanded around -inf to get
   \[\color{red}{\left(\frac{{\left(\left|\frac{-1}{d}\right|\right)}^2 \cdot \left(d \cdot a\right)}{{c}^{4}} + \frac{b}{c}\right) - \frac{d \cdot a}{{c}^2}} \leadsto \color{blue}{\left(\frac{{\left(\left|\frac{-1}{d}\right|\right)}^2 \cdot \left(d \cdot a\right)}{{c}^{4}} + \frac{b}{c}\right) - \frac{d \cdot a}{{c}^2}}\]

7. Applied taylor to get
   \[\left(\frac{{\left(\left|\frac{-1}{d}\right|\right)}^2 \cdot \left(d \cdot a\right)}{{c}^{4}} + \frac{b}{c}\right) - \frac{d \cdot a}{{c}^2} \leadsto \left(0 + \frac{b}{c}\right) - \frac{d \cdot a}{{c}^2}\]
   6.2
8. Taylor expanded around inf to get
   \[\left(\color{red}{0} + \frac{b}{c}\right) - \frac{d \cdot a}{{c}^2} \leadsto \left(\color{blue}{0} + \frac{b}{c}\right) - \frac{d \cdot a}{{c}^2}\]
