A boy named Alex plans to give a rose with a beautiful ring to his sweetheart Rosie.
But Rosie likes a specific kind of rose with a ring such that -
If the rose is considered as a 2-D circle , the ring is a point with coordinates , the power of the point (ring) is '101' with respect to the circle(rose). [2- D Geometry]
Alex collects 5 roses with one ring each with coordinates and opts to select the appropriate rose, which his sweetheart Rosie would like on Valentine's Day.
The collected roses had the following equations:
Rose R :
Rose O :
Rose S :
Rose I :
Rose E :

The name of the film is 'Love, Rosie'.
Power of point R(-3 , -5) with respect to circle of rose S
= (-3)^2 + (-5)^2 - 6(-3) - 8(-5) + 9
= 9 + 25 + 18 + 40 + 9
= 101 :)
Hence rose 'S' is the appropriate one.
Don' underestimate the power of a ring along with a rose :P :D :)
