JEE Math Practice Question
The locus of mid-points of the line segments joining ($$-$$3, $$-$$5) and the points on the ellipse $${{{x^2}} \over 4} + {{{y^2}} \over 9} = 1$$ is :
- A.$$9{x^2} + 4{y^2} + 18x + 8y + 145 = 0$$
- B.$$36{x^2} + 16{y^2} + 90x + 56y + 145 = 0$$
- C.$$36{x^2} + 16{y^2} + 108x + 80y + 145 = 0$$
- D.$$36{x^2} + 16{y^2} + 72x + 32y + 145 = 0$$
