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%5E2+%2B+y%5E2+%2B+4x+-+y+=+10
%28x%5E2+%2B+4x%29+%2B+%28y%5E2+-+y%29+=+10
%28x%5E2+%2B+4x+%2B+4%29+%2B+%28y%5E2+-+y+%2B+1%2F4%29+=+10+%2B+4+%2B+1%2F4
%28x+%2B+2%29%5E2+%2B+%28y+-+1%2F2%29%5E2+=+57%2F4
The center is at (-2, %281%2F2%29) and the radius is highlight%28sqrt%2857%29%2F2%29.
