x²+[x]²-2[x]x+y²-20=0

which is a circle of radius=√20 and centre ([x],0)

maximum value of [x] can be upto 4,and the minimum value is -5

okie sir,i will try.

tx sir,i got the soln after seeing the soln for {x}²+y²=1.

i feel dat the graph will be better if he can give the eqn of the four lines parallel to x axis.
