Question

If a+1/a=1 then A3+1=

Answer 1

Answer:

No(0)Since a+1/a=1, we can 1/a=1-a ---- assume equation (1)

Now, taking square on both side

we get

a^2 + 1/a^2 + 2=1

a^2 + 1/a^2 = -1 put the value of 1/a form equation (1)

a^2 + (1-a)^2=-1

a^2 + 1 + a^2 -2*a=-1

2*a^2 - 2*a=-2

a^2 - a =-1

a(a-1)=-1

a=-1,0

Here a=0 mean, there is no meaning

so, finally a=-1

and Answer is: a^3=-1

Answer 2

Ans-1 is the answer I think
