Question

In the following find the centre and radius of the circles: $2x^{2} +2y^{2} -x=0$

Answer 1

here is answer take the following step( s) into consideration !!!!

2x² + 2y² -x = 0

so we know it cofficent must be same

so that divide by 1/2

so we have

x² + y²- 1/ x

kindly notice here y = 0 , and c = 0 here



center will be => ( -g , - f ) = ( 1, 0 )

radius => √ g² + f²-c


=> ✓ 1² +0 ²+ 0²

=> 1

hope it help you !!

thanks !!
