Hey,

Nigitha , put x=1.

We have 2³-[2²-1]=8-[3]=5 on the L.H.S

and on the R.H.S we have 2²+1=5

So,x= -1 is not the only answer. YOU ARE WRONG......!!!!!!!!

And Aditya, put x=0

L.H.S. = 2²-[2-1]=4-1=3

R.H.S. = 2+1=3 , hence x=0 satisfies the equation.

YOU ARE WRONG ADITYA............!!!!!!!!!!!!
