Question 1063588
Q: Rewrite this equation OF A CIRCLE IN STANDARD FORM
x^2 +y^2 +4x-y=10
and then give the center and the radios of the circle and graph.

Tutorial:
{{{x^2 + y^2 + 4x - y = 10}}}
{{{(x^2 + 4x) + (y^2 - y) = 10}}}
{{{(x^2 + 4x + 4) + (y^2 - y + 1/4) = 10 + 4 + 1/4}}}
{{{(x + 2)^2 + (y - 1/2)^2 = 57/4}}}
The center is at (-2, {{{(1/2)}}}) and the radius is {{{highlight(sqrt(57)/2)}}}.
Graph: 
{{{drawing( 300, 300, -8, 8, -8, 8, grid( 1 ), circle( -2, 1/2, sqrt(57)/2 ))}}}
