(({(x−2)+yi}^2 )/((x+1)−yi))×(((x+1)+yi)/((x+1)+yi))  (({(x−2)+yi}^2 {(x+1)+yi})/((x+1)^2 +y^2 ))  (({(x−2)^2 +2(x−2)yi−y^2 }{(x+1)+yi})/((x+1)^2 +y^2 ))
$$\frac{\left\{\left(\mathrm{x}−\mathrm{2}\right)+\mathrm{yi}\right\}^{\mathrm{2}} }{\left(\mathrm{x}+\mathrm{1}\right)−\mathrm{yi}}×\frac{\left(\mathrm{x}+\mathrm{1}\right)+\mathrm{yi}}{\left(\mathrm{x}+\mathrm{1}\right)+\mathrm{yi}} \\ $$$$\frac{\left\{\left(\mathrm{x}−\mathrm{2}\right)+\mathrm{yi}\right\}^{\mathrm{2}} \left\{\left(\mathrm{x}+\mathrm{1}\right)+\mathrm{yi}\right\}}{\left(\mathrm{x}+\mathrm{1}\right)^{\mathrm{2}} +\mathrm{y}^{\mathrm{2}} } \\ $$$$\frac{\left\{\left(\mathrm{x}−\mathrm{2}\right)^{\mathrm{2}} +\mathrm{2}\left(\mathrm{x}−\mathrm{2}\right)\mathrm{yi}−\mathrm{y}^{\mathrm{2}} \right\}\left\{\left(\mathrm{x}+\mathrm{1}\right)+\mathrm{yi}\right\}}{\left(\mathrm{x}+\mathrm{1}\right)^{\mathrm{2}} +\mathrm{y}^{\mathrm{2}} } \\ $$$$ \\ $$
