Number of points of intersection of the hyperbolas x2−2x−y2+4y−4=0 and x2−2x−y2+4y−2=0 is/are
Open in App
Solution
x2−2x−y2+4y−4=0........... (i) x2−2x−y2+4y−2=0 ........... (ii) (i)−(ii), gives −4−(−2)=0 −4+2=0 −2=0 which is false Therefore, given hyperbola do not intersect each other at all Therefore No. of points of intersection=0
