a n b r not sm special parameters dis r just constants right!
then just by looking at the question,
the points shud come symmetrical in a n b (juzz coz a n b has no special relations to x or y or to any axis)
dis is a rectangular hyperbola. i applied two methods:
1st) rotated it by 45 deg anticl. n got the eqn
x^2-y^2 = (a^2+b^2)/2 n found its focus
den again rotated it by 45deg clockwise n found the original focus.
2nd) if u draw it, u'll find vertices r points closest to origin on the hyperbola
applied distance formula, found its minima n got the vertices
added ae to it n got the focus
note that ae is dist of focus frm vertices along y=x
by no way i'm getting a soln w'out roots
