Analyzing +4 | -1

The radical axis of the circles

x^2+y^2+2 g x+2 f y+c=0

and

2\left(x^2+y^2\right)+3 x+2 y+2 c=0

touches the circle

x^2+y^2+2 x+2 y+1=0

, if

View answer and explanation

Correct option: B

g=\frac{4}{3}

and

f=\frac{1}{2}

Option B (

g=\frac{4}{3}

and

f=\frac{1}{2}

) is correct because these values satisfy the condition for the radical axis to touch the third circle.
