X2 - Y2 + 4X = 0

IF WE SOLVE THE EQN ,WE GET THE EQN OF A HYPERBOLA WITH ECCENTRICITY = 0.

CAN ANY ONE EXPLAIN IF A HYPERBOLA CAN HAVE ECCEN.= 0.

IF IT IS POSSIBLE CAN YOU SHOW IT GRAPHICALLY

use condition for equation ax2+by2+2hxy+2gx+2fy+c=0

 to represent a pair of lines

abc+2hgf-af2-bg2-ch2=0

this condition is satisfied hence it represents a pair of lines and not  a HYPERBOLA of zero eccentricity.

thankx for showing interest

ACTUALLY ,I HAD BEEN WRONG IN CALCULATING THE ECCENTRICITY WHICH ACTUALLY IS SQUR ROOT OF 2 AND NOT ZERO

OTHERWISE IT IS AN EQUATION OF AN HYPERBOLA ONLY

I think it is not a continous line but two rays moving outward.

Mohit you may consider that a normal hyperbola arms are compressed to x - axis.

The dark line is your curve.

HEY MOHIT ! THE GIVEN EQUATION REPRESENTS A RECTANGULAR HYPERBOLA OF ECCENTRICITY SQ. ROOT OF 2 .
