What is the standard form of the equation x^2 + y^2 + 10x -8y +5 = 0
**
x^2 + y^2 + 10x -8y +5 = 0
complete the square
(x^2+10x+25)+(y^2-8y+16)=-5+25+16=36
(x+5)^2+(y-4)^2=36
This is an equation of a circle of the standard form: (x-h)^2+(y-k)^2=r^2, (h,k) being the (x,y) coordinates of the center, r=radius
