Question

A=x-1/x+1then the value of A-1/A​

Answer 1

Step-by-step explanation:

f(f(x))=

x+1

ax

+1

a

x+1

ax

=

x+1

ax+x+1

x+1

a

2

x

=

ax+x+1

a

2

x

Since, f(f(x))=x, we have,

ax+x+1

a

2

x

=x.

Simplifying the equation we get,

a

2

x=(a+1)x

2

+x

∴(a+1)x

2

+(1−a

2

)x=0

or (a+1)x(x+1−a)=0

Hence the only possible value is a=−1
