If
[tex] \frac{ \alpha + 1}{ \alpha - 1} + \frac{ \alpha - 1}{ \alpha + 1} = x [/tex]
and
[tex] \frac{ \beta + 1}{ \beta - 1} + \frac{ \beta - 1}{ \beta + 1} = x[/tex] then value of [tex] \alpha \beta [/tex]
is equal to:. [tex](\alpha \: \: is \: not \: equal \: to \: \beta )[/tex]
Options:
1) [tex] \frac{x + 1}{x - 2} [/tex]

2) [tex] - \frac{(x + 2)}{x - 2} [/tex]

3)[tex] \frac{x - 2}{x + 2} [/tex]

4) None of these
