Bhaiya where is the Question on locus (part 1) and only 11 lessons are come not 13 lessons
sir that solution is completely wrong, you assume that the curves are circles but condition for circles be h=0,a=b but tha question doesn't satisfies that

it is completely correct, hxy=0 thus h=0 and a=b=1
Look at the beauty of math, In last question curves do not even intersect at 4 points for any real value of a. : P and at a=-4 they do not even intersect. but still according to theory they intersect at 4 con-cyclic points. Not complaining of anything just talking about beauty of math lol.
Locus of centre: x^2=8y-8. Shape is parabola.
parabola => x^2 = 8y - 8 .
