Answer 1

$\frac{2x^{2}+x+3}{ x^{2} +2x+1} - \frac{x+2}{x+1}\\\\ \frac{2x^{2}+x+3}{ (x+1)(x+1)} - \frac{x+2}{x+1}\\\\ \frac{2x^{2}+x+3}{ (x+1)(x+1)} - \frac{(x+2)(x+1)}{(x+1)(x+1)}\\\\ \frac{2x^{2}+x+3-(x^{2}+3x+2)}{ (x+1)(x+1)}\\\\ \frac{x^{2}-2x+1}{ (x+1)(x+1)}\\\\ \frac{(x-1)(x-1)}{ (x+1)(x+1)}\\\\ \frac{(x-1)^{2}}{ (x+1)^{2}}\\\\ (\frac{x-1}{x+1}) ^{2}$
