Question

The equation of the circle passing through the origin and the points of intersection of the circles $x to the power of 2 end exponent plus y to the power of 2 end exponent minus 4 x minus 6 y minus 3 equals 0 comma$ $x to the power of 2 end exponent plus y to the power of 2 end exponent plus 4 x minus 2 y minus 4 equals 0$

$x^{2} + y^{2} + 28 x + 18 y = 0$
$x^{2} + y^{2} -$ 18x‐28y $= 0$
$x^{2} + y^{2} - 28 x + 18 y = 0$
$x^{2} + y^{2}$ ‐28x‐l8y $= 0$

The correct answer is: $x to the power of 2 end exponent plus y to the power of 2 end exponent$ ‐28x‐l8y $equals 0$
