Answer 1

$T = ( \frac{a+b}{a-b} + \frac{a-b}{a+b} ) ( \frac{ a^{2} - b^{2} }{ a^{2} + b^{2} } )$

$T = (\frac{ (a+b)^{2} + (a-b)^{2} }{(a-b)(a+b)} ) ( \frac{ a^{2} - b^{2} }{ a^{2} + b^{2} })$

$T = \frac{2( a^{2}+ b^{2}) }{ a^{2} - b^{2} } ( \frac{ a^{2} - b^{2} }{ a^{2} + b^{2} })$

Simplificamos y nos quedaria :

 T = 2
