Question

Find the centre and radius of the circle 2x2+2y2-x=0

Answer 1

hope it will help you

Answer 2

Answer :

$\therefore$ 2x² + 2y² - x = 0 .

==> 2 ( x² + y² - x/2 ) = 0 .

==> 2/2 ( x² + y² - x/2 ) = 0/2 .

==> x² - x/2 + y² = 0 .

==> ( x² - x/2 + (1/4)² ) + y² = (1/4)² .

==> ( x - 1/4 )² + ( y - 0 )² = (1/4)² .

Hence, centre ( -1/4 , 0 ) and radius = 1/4 .
