Questions
The equations of the circles which touch both the
axes and the line are
a
x2+y2±ax±ay+a24=0
b
x2+y2+ax±ay+a24=0
c
x2+y2−ax±ay+a24=0
d
none of these
detailed solution
Correct option is C
Since the circle touches both the axes and the linex =a. Therefore, coordinates of its centre are (a/2,±a/2) and radius a/2. Hence, the required circles arex−a22+y∓a22=a22⇒x2+y2−ax±ay+a24=0Talk to our academic expert!
