write the standard equation for each circle. then state the coordinates of its center and give its radius
\n" ); document.write( "x^2+y^2+4y=12
\n" ); document.write( "------------------
\n" ); document.write( "(x-0)^2 + y^2 + 4y + 4 = 12 + 4
\n" ); document.write( "--------------------------------------
\n" ); document.write( "(x-0)^2 + (y+2)^2 = 16
\n" ); document.write( "----
\n" ); document.write( "Center:: (0,-2) ; radius = sqrt(16) = 4
\n" ); document.write( "---------------
