$A+B \: = \frac{x + 1}{x - 1} + \frac{x - 1}{x + 1} \\ \\ \\ \\ = > \frac{ {(x + 1)}^{2} + {(x - 1)}^{2} }{(x - 1)(x + 1)} \\ \\ \\ \\ = > \frac{ {x}^{2} + 2x + 1 + {x}^{2} - 2x + 1}{ {x}^{2} - 1 } \\ \\ \\ \\ \\ = > \frac{ {2x}^{2} + 2}{ {x}^{2} - 1 } \\ \\ \\ \\ = > \frac {2( {x}^{2} + 2)}{ {x}^{2} - 1 }$
