The Total solution for NCERT class 6-12
Find the centre and radius of the circle 2x2┬а+ 2y2┬атАУ┬аx┬а=0
The equation of the given circle is 2x2┬а+ 2y2┬атАУ┬аx┬а=0.
, which is of the form (x┬атАУ┬аh)2┬а+ (y┬атАУ┬аk)2┬а=┬аr2, where┬аh┬а=┬а,┬аk┬а= 0, and┬а.
Thus,the centre of the given circle is, while its radius is┬а.
,┬аk┬а= 0, and┬а
.
, while its radius is┬а
