Question

find the center and radius of a circle whos equation is x^2+y^2+88=8y-22x
if it helps heres the formula
(x-h)^2+(y-k)^2=r^2

Answer 1

youre going to have to complete the squares on x and y to condense it

Answer 2

or, let y=0 and solve the quadratic in x

then let x=0 and solve the quadratic in y

the axis of symmetry for x and y will cross at the center, and the distance from the center to any of the 4 known points defines the radius
