The equation of the circle whose one diameter is

PQ

, where the ordinates of

P,Q

are the roots of the equation

{x^2} + 2x - 3 = 0

and the abscissae are the roots of the equation

{y^2} + 4y - 12 = 0,

View answer and explanation

Correct option: A

{x^2} + {y^2} + 2x + 4y - 15 = 0

Option A

{x^2} + {y^2} + 2x + 4y - 15 = 0

is correct because it represents the circle with the given diameter endpoints derived from the roots of the provided equations.
